Problems since the latest update

Hello everyone,

Since the latest update, I have encountered the following problems several times and I can rule out that the problem is from our side:

1. throw-ins
If you select a player with the right stick during a throw-in, the game starts to lag until you were able to throw or the player throws automatically (time expired).

2. matchmaking coop
I often play with my friend in Rivals Coop because we have fun and it's easier to win. However, the matchmaking takes forever. If you're lucky, you'll find an opponent after about 5-10 minutes. We have switched off crossplay, because crossplay causes lags on PC.  With crossplay we need about 5 minutes.

3. matchmaking coop connection
Since the latest update, my friend and I always have connection problems on the same time in a game. The ping (ms) is usually 10-20 but every few seconds the ping jumps to 40+ms and you can see the yellow/red connection indicator at the top.

We both play on PC, have the latest drivers, both play via Lan cable and our PC's meet the requirements. 
I would be delighted to receive an answer.

Best regards
