It has been reported to Wyze and there are other threads discussing the issue, linked below.
I also experienced this once. It seems to be an issue with the server authentication and verification process for the active subscription failing.
Some have been able to complete the setup again, which is recommended and won’t mess anything up. Others, like me, got a failure upon setup.
I cleared the cache in the app, signed out, forced the app closed, restarted the phone, signed back in, and haven’t experienced it again.
