I have problems with project-gc for about 1 hour,too. Previously, I could use my statistics and various search functions for caches without any problems. Now I am to authorize myself again and again at Geocaching.com. Proposing to break this loop, clearing cache, logging out of Geocaching.com and project-gc, or revoking existing authorizations on Geocaching.com and rebuilding them did not work.
So that there are no misunderstandings: I had not used premium features. But almost all functions in the menu bar are greyed out except for "Home"
Is there a common problem with Project-GC? When will the issues be resolved?
I thank you in advance for your help.
