Hey,
I have tried removing the sync from all devices (and removing the data), but afterwards I get the same error.
If I connect via desktop, a new Enpass-folder is created. If I only connect via android-app (same user), no Enpass-folder is created and it fails with the error 908401 even though all login-data is correct.
I have also tried creating a new account. Again it works just fine on desktop but not at all in the android-app. I will send you a PM with the login-data for that account for you to verify, as requested.
Thanks.
