Matchmaking not working for me at all

I can play with my friends, but that’s it. Every time I go to standard or try duos it doesn’t work. This is consistent over my tablet version and PC version

This is not a good description of the problem.

What happens, exactly?

Does the matchmaking wheel spin forever without finding an opponent?
Do you get an error?
Does the game freeze up?
Does the game crash?
Do the Blizzard police come and cart you off to jail?

It pops up with an Error message and says to wait a few minutes. So I do and it continues. That’s all I got, capitan
