What's Wrong?

I am on Claude mac app, started a session using opus4.7 1M max and it started getting really boggy with tons of retries and eventual API Error: Unable to connect to API (ECONNRESET) errors in the same session.

The 5 hour limit usage jumps up a lot every time I tried sending a new message in the same session.

I'm on latest version of claude mac app 1.5354.0

looks like I am not the only one.
