Feedback:

For some reasons, for a few weeks now I can’t relogin to Web Bear. It worked fine for months before, but now I get stuck with this error:

I dailydrive Zen, so I tried with Helium (chromium based) and Safari, but I always get the same error, even with all extensions off / on blank profile.

FWIW, I have ADP enabled on my Apple account.

Is it something related to your implementation of the auth or an Apple issue?

my bad, just saw it might be duplicated of these:

but if ADP should prevent access to Bear Web, why can I still access it on my logged in session? and why did it worked for months too?
