I tried to add friends early in the morning when I wake up, found all of them in few seconds..
Yesterday evening, it was impossible.
Seems the server are too busy with the pandemic.. Take care guys.

I have the exact same problem.

I've experienced this multiple times as well over the past few days. Also get "error reported," can play for one turn and then it freezes.

@GregorC Thanks for the feedback. It would be great to know what version he/she is using since this issue seems to have special circumstances in which it occurs.
