Agents can no longer send replies in Instagram conversations on Chatwoot Cloud while the temporary Meta platform restriction is active. The reply box locks into Private Note mode — the same behavior as an expired 24-hour reply window — so teams can still collaborate internally, with the existing amber restriction banner above the conversation explaining why. Self-hosted installations are unaffected. Follow-up to #14974. ## How to test 1. On a Chatwoot Cloud environment (`isOnChatwootCloud` true), open any Instagram conversation. 2. The composer should be locked to Private Note mode: the Reply/Private Note toggle is disabled, and sending creates a private note — even for conversations within the 24-hour reply window. 3. Switching between conversations should keep the composer in Private Note mode for Instagram conversations. 4. On a self-hosted environment, Instagram conversations should behave as before (reply allowed within the messaging window). Co-authored-by: Muhsin <12408980+muhsin-k@users.noreply.github.com>
