Since the latest Codex update, Codex Mobile can connect to my Codex Mac instance and can start new conversations, but one existing conversation fails to load.
Error:
CodexAppServer.CodexClientError error 11
"Fehler beim Laden der Nachrichten"
Only this specific conversation is affected. New conversations work. Please check whether the thread history/event timeline became incompatible or corrupted after the update.
