Online Issues Last Few Days, Cross Play Lag?

So I’ve been having problems the last few days with online matches lagging and eventually dropping out. I’m confident my internet connection is fine and I’ve rebooted Xbox / modem many times. I’ve got a suspicion the bad connections are with PC players (I’m on Xbox), but I can’t confirm this. Generally it seems exhibition matches with cross play disabled are better, maybe total coincidence.

Maybe unrelated but games seem to be taking longer to find online too. I’m curious if there’s been a change to how matchmaking is done behind the scenes to accommodate PC players.

I’m in the UK. It’d be good to know if anyone else has similar experience the last few days.
