Within days of each other in early October 2026, Meta began trialing app-opening experiences that drop users straight into full-screen Reels — an opt-in setting on Instagram and an opt-out test on Facebook in India and Indonesia — the same strategic bet pressed across two different apps.

Over a few days in early October 2026, Meta was reported to be testing Reels-first app openings on both of its flagship apps at once. Social Media Today reported Instagram's test on October 5, 2026 — an opt-in setting that opens the app straight into a full-screen Reels feed, spotted by app researcher Radu Oncescu. TechCrunch reported Facebook's version on October 6, 2026 — a trial that drops some users into a full-screen, video-first experience when they open the app. Taken together, they are the same idea aimed at two different surfaces: make a vertical video, not a grid of posts, the first thing a user sees.
The mechanics differ by app. On Instagram the Reels-first layout is something a user turns on; Stories stay along the top and the traditional feed is one swipe away, and you can switch back at any time. On Facebook the test is running in India and Indonesia — video-heavy markets outside the U.S. — with users able to opt out and the classic feed kept as a second tab; Meta has said it will explore bringing the experience to the United States next year. Facebook head Tom Alison outlined that video-first direction in July, describing a plan to put a subset of people who want more video "into full-screen video the moment they open the app," starting in video-heavy countries. Both tests are limited and can change, so confirm what is live in your market before planning around a single detail.
What makes this a Meta-wide pattern rather than two unrelated experiments is how much groundwork already pointed here. Meta had already changed Facebook so that all new videos post as Reels regardless of length or format and renamed the app's Video tab to "Reels." On Instagram, the company says more than half of in-app time now goes to watching Reels, and the format is reported to account for essentially all of its recent engagement growth; it also ran an earlier opt-in Reels-first test in India in 2025. A Reels-first home screen is the logical endpoint of both trajectories — and it lands the same week TikTok and YouTube Shorts already open to vertical video by default, which means the front door of nearly every major app is converging on the same format.
Nothing here is a forced global default today. Both tests preserve an escape hatch — opt-in on Instagram, opt-out plus a second-tab classic feed on Facebook — and availability is narrow. But Meta choosing to run the same play on two apps simultaneously is the signal: short-form vertical video is becoming the default discovery surface across its family, not a feature living in one tab.
Read the two tests as one message: across Meta, the first thing a viewer meets is becoming a full-screen vertical video. When that is true on Facebook, Instagram, TikTok, and YouTube Shorts at once, the scarce thing is not another clip — it is a consistent on-camera identity that reads as unmistakably you every time one of those front doors opens. That identity layer is where [Kompozy](/) starts. Its AI Influencer persona pool and the [Persona Brief](/glossary/persona-brief) lock a single face, voice, and style across everything it makes, so a week of Reels does not look like a week of different accounts. You show up on camera consistently without filming daily: [Persona Shorts](/glossary/persona-shorts) put a face-locked avatar with auto-captions in front of a script you approve, Persona HeyGen and Persona VFX HeyGen extend that into longer, multi-scene cuts with a generative hook, and [Persona Frames](/glossary/persona-frames) composite the same avatar into a brand-exact [HyperFrames](/glossary/hyperframes) template — all the same persona, so recognition compounds instead of resetting.
Because Meta's move is family-wide, the distribution job is to make that one identity native to every front door and still stock the feeds sitting one tab behind them. [Autopilot](/glossary/autopilot) reframes each short with platform-native copy and captions and schedules it to Facebook Reels, the Instagram Reels-first home, TikTok, and YouTube Shorts from one queue behind a per-post review gate — while the same engine keeps the supporting surfaces full with [Carousel Posts](/glossary/output-buckets), photo and quote graphics, blogs, and newsletters that still live in the classic feeds. Meta is turning its whole family video-first; Kompozy is how one recognizable brand persona claims every opening screen at once and keeps the rest of the feed fed too.
Not as a forced global default yet. As of early October 2026, both are tests: Instagram's Reels-first opening is an opt-in setting a user turns on, and Facebook's is an opt-out trial running in India and Indonesia with the classic feed kept as a second tab. Both preserve a way back to the traditional feed, and availability is limited — but Meta running the same play on both apps points at video-first openings being the direction for its family.
Instagram's is an opt-in layout: you enable it, Stories stay along the top, and the traditional feed is one swipe away. Facebook's is an opt-out test currently in India and Indonesia — video-heavy markets — that drops included users into full-screen video on open, with the classic feed as a second tab and a U.S. look planned for next year. The shared idea is making a vertical video, not a grid of posts, the first thing a user sees.
Build a steady supply of on-brand vertical video and keep your on-camera identity consistent across clips, since the first impression on these apps is becoming a full-screen short. Because TikTok and YouTube Shorts already open to vertical video too, the same shorts can win multiple front doors at once — so producing short-form well, and publishing it everywhere from one queue, is the practical response. A content engine like Kompozy generates face-locked persona video from a script and schedules it across the eight social platforms plus blog and email.
Yes, in a supporting role. Both tests keep the traditional feed reachable — Stories stay pinned on Instagram and Facebook keeps its classic feed a tab away — so carousels, photos, and text posts still have a home. They just stop being the first thing a video-first user sees, which shifts the lead role to short-form video while the rest of the feed continues to carry depth.
