For me, I run 2 servers, one of them says connected in Management Access but not in the My Servers site, the other one wasn't connected either after this update. I tried resetting my password, disabling MFA and try to connect it. In the end, I received an error saying:
Error: {"message":"Request failed with status code 406","data":{"error":"GUID already registered to another email (not matching
[email protected])"}}
Doesn't make any sense to me, because they were both connected just fine before this update with my account.
