We’ve been using Auth0 in our iOS apps without issue for some time, but we’ve recently onboarded several new groups of users and some devices are persistently showing an error when we attempt to login using WebAuth. Specifically, it says Authorization Extension: "0" is not allowed be empty. Obviously, this is very cryptic and doesn’t give us much to go on.
Since the error pops up immediately and doesn’t even get to the point where the user inputs an email, it doesn’t suggest an issue with their profile configuration unless there’s something cached that’s throwing things off. We also call clearSession before all login attempts since the devices are shared between users and we don’t want passwords to be cached. Has anybody seen anything like this?
