I am having difficulty logging in - most recently to SOTA mapping in order to use the profile feature. I am sure last time I used it no login was needed but this time it seemed to be. When I did try I received the message:-
Unexpected error when handling authentication request to identity provider.
in response to clicking on the login window which was already populated with remembered username and password.
Using Firefox 60.7.2esr (64-bit) on Linux openSUSE Leap 15.0 with all recent updates.
This has happened earlier in the day but I circumvented it; that does not seem possible for the mapping.
