The amber We lost connection with your creator account banner means Substy needs you to reconnect the selected creator before account-dependent features can continue normally.
Use the current reconnect guide for the full workflow: Reconnect a disconnected creator account.
Messages, AI Chatter, automations, statistics sync, scheduled content, and other platform-dependent actions may pause or fail until the creator is reconnected.
Your Substy setup is not removed just because the creator disconnected.
If verification is requested during reconnect, complete the prompts shown for that creator account.
