### What's Wrong?

I cannot log in to my Claude account .
I am taken automatically to the let’s create your account page.
This issue has now been going on for five days and now I cannot use Claude code or connect Claude code to my console and all iOS app sessions are disconnects and cannot reconnect without log in

### Additional Information

_No response_
