What's Wrong?

Business account with Premium tier. I have sufficient extra usage allocated on my account to cover intended usage, but my sessions are being blocked with 'Usage limit reached - resets at 6:00pm' which is when my weekly usage of plan tokens will reset.

Plan usage shows Weekly - all models at 100%, resets in 6h. The Claude desktop app blocks any interaction with the session despite having allocation remaining.

I believe this is a bug where the Claude UI is using the token limits from the Premium plan to gate access to the sessions, rather than the extra usage capability.

What Should Happen?

After usage has been depleated from the premium plan, the UI should switch to extra usage and not block access to the thread.

Error Messages/Logs

Steps to Reproduce

1. Be on Premium business plan
2. Have extra usage enabled and funded
3. Use up weekly allowance
4. See that threads are blocked pending the counter reset, despite balance existing

The same applies on Web sessions or Cloud sessions accessed through Claude Desktop
