Publish shows missing media, large file, offline, or readability warnings

What you may be seeing

• Publish succeeds but returns one or more warnings.

What usually causes it

• A scene references deleted/nonexistent media.
• A referenced original exceeds the player's 250MB cache skip threshold.
• An asset is hosted outside CanvasRelay and cannot be guaranteed for offline playback.
• An online-only widget is present.
• Text size/contrast falls below the readability checks.

Do this

1. Read each warning before treating the release as production-ready; warnings do not stop Publish.
2. Replace/remove missing media references.
3. Compress or replace oversized media so players can cache it reliably.
4. Move important external media into the CanvasRelay Media library when you need offline reliability.
5. For online-only widgets, accept that they need connectivity or use an offline-capable alternative.
6. Adjust text size/contrast when readability warnings matter at the actual viewing distance.

You know it is fixed when

• A later publish has only warnings you intentionally accept, and physical screens render the expected content.
