Hi @vooni - just caught up with this thread. You said you’re able to log in on the web. Can I ask you to try to log in on your Android with another account? If you don’t have a friend with an account to borrow, please just create a new one on the web, and then test out whether you can log in with it on Android. (Asking this to figure out if your case is similar to an existing login-related case we’re investigating.)
Also, could we please continue troubleshooting via support@mapillary.com? It’s a better channel for issue-solving than the community forum. I’ll be looking forward to your email!
