Instagram, Facebook, Threads

Instagram, Threads and Facebook connect directly, each with its own sign-in: the “Connect …” button in Settings → Channels opens the platform's screen, you confirm access — and the account appears in the list. Routes via Zernio, Buffer and SmmBox remain for those who already set them up.

What works

• Instagram directly: feed, carousel up to 10 files, story and Reels — the format is chosen in the post card next to the channel. Post statistics refresh hourly, DMs come into “Chats”.
• Threads directly: text, image, carousel; replies under posts — in “Chats”; per-post statistics. Chains: a post and its continuations are published as a thread (see Planner).
• Facebook directly: publishing to a Page and basic metrics.
• Via Zernio, Threads has reach and the daily curve; via Buffer, Instagram has reach and saves.

What's missing

• Instagram doesn't accept a post without an image — the service warns right away; Reels need a video file.
• Instagram must be professional (Business or Creator) — the only requirement for the account.
• Threads: 500-character limit, no formatting, and the platform has no direct messages at all.
• Instagram doesn't always return comments to apps: the counter under the post grows while the list may be empty.
