Group for Multiplayer does not work

Ever since Sultans Ascend came out, I can’t do multiplayer with friends properly. What does work are custom games. But I cannot create a group to play quickmatch or ranked together.

My friends are usually shown as offline (apparently a known bug). If I send invitations, they don’t see it. If they send me invitations, I get them and can even accept. They get a notification that I accepted, but nothing happens, i.e. we aren’t in a group together.

We both have the DLC and Windows 11. LMK if there’s any other useful info you need.

And please other viewes, LMK if you have the same or if you found any workarounds.

We figured out what happened. Apparently my friend accidentally blocked me on Steam. But it’s fixed now and we can invite each other again.

Still, this is maybe worth a consideration. It was very hard to debug since there is no messaging, it just “doesn’t work”. If there was any hint that this is about blocking, we wouldn’t have tried for 2 weeks.
