I like participating in groups and team matches through these groups, but I find it really difficult to review the results of those matches.

I'm usually a pretty fast player and I finish my games pretty quick, but once I've completed my games, the outcome of that match often goes unnoticed as I don't get a notification of "Your team won the match against team X! Click here to view the final match results".

It seems silly to not be able to easily find the results of team matches that I myself played in, especially when it can potentially take weeks and months for each match to play out.

Agreed! Also, finding matches I have joined but have not started and even matches in progress by team.
