I have the same problem, as of 4 days ago, with Brave browser. I can’t see any games, live or correspondence.
The problem occurred when I checked off some of the preferences in the games section. To try to fix the problem I put them back, pressed refresh, refreshed the page, no luck so far.
No problem with Safari, but I’ve used Brave for over 6 months on OGS.
Any ideas for fix, other than to use Safari?
