What feature did you use:
Clicked my first time link, logged in with Apple (via system prompt on iOS or via login window with FIDO 2FA on Firefox, then after login accepted by Apple, the below auth issue occurred
Hi, and thank you for the report.
That authentication error is generated by Apple, so in a manner of speaking it’s out of our control. 2FA is fine in general, on the other hand, Advanced Data Protection affects access to the iCloud API, do you have ADP enabled as well?
Hi and welcome to the conversation!
So to clarify, the short version is that, yes, sadly, ADP will prevent access to Bear Web, at least in this phase. We’re actively looking for a solution, and rest assured we’ll keep you posted on any improvement.
