Yeah, matchmaking is fixed for me as well. I'm not certain if it was the patch - a few people told me prior to the patch that they experienced the same problem but it eventually fixed/corrected itself. Whatever the case,, I'm just glad it works now.
Now I just wish it wouldn't disconnect me with connection issues 30 minutes into a match!
Interestingly enough, it's never happened in private match games - just with randomers. 🤔
