macOS remote conversation stuck on Thinking #46591

ChatGPT/Codex 26.915.31945 on MacBook, connected to an iMac. Same account on iPhone. App reports up to date.

Remote conversation remains on Thinking on MacBook while completed replies appear on iPhone. Connection shows Connected. New local chats work.

Restarting, switching conversations and pressing Stop did not resolve it. Reconnecting the iMac temporarily refreshes history, then updates stall again.

Expected: new messages and completed replies appear on both clients.
