Image details
- Feed images must be JPEG.
- Aspect ratio outside 0.8–1.91 is letterboxed during media prep so Graph publishing can accept the file.
- Width between 320 and 1440 pixels is preferred.
Video details
- Reels use the 300 MB / 3–900 second product envelope.
- Carousel video items use the stricter 100 MB / 60 second product caps.
- Keep scheduled media URLs publicly reachable until publish completes.
Replies on Instagram
With Instagram connected, Replies loads comments (including nested follow-ups when available) so you can respond in Omni Writes. If comments fail with a permission error, reconnect Instagram and approve comment scopes.Common problems
- Media could not be fetched: Keep the scheduled URL public until publish completes; re-upload and retry.
- Carousel failed: Confirm 2–10 items and that every child is ready.
- Wrong image format: Convert feed images to JPEG.
- Aspect rejected: Prefer 4:5–1.91:1; Omni Writes letterboxes when needed.
- Missing usernames: Reconnect with current comment permissions.
- Authorization expired: Reconnect from Channels, then retry from Calendar.
