I am having the same problem 2 days ago I got one match.  I tried to play probably 40 times but couldn't.  I could see friends online, but could not send them invites to play.  I got the message to go to ea.com/unable to connect, but the page was not found somehow.  Anyway last night I played like 4 matches in a row no waiting, then this morning again I can not find a match, even though I am clearly connected to the internet and I can see that friends are currently playing Fifa 20 on my switch, I am unable to play.  Please fix soon EA.
