Monitoring
We've deployed a fix and are monitoring the solution.
Investigating
We're investigating an issue where publishing can get stuck waiting for Bolt to finish current work. Some users may also see editing blocked while this occurs.
As a workaround, reloading the page and retrying publish may help (note: reloading can risk losing unsaved changes). We've shipped mitigations to add diagnostics and a 5-minute timeout so publishes don't hang indefinitely, and we're actively monitoring the situation.
