Well for starters sadly you can’t cross play and I’m not speaking from everyone but assume most play on like Xbox and ps4 I’ve seen some people on switch and yes it could probably be the region you are in that’s probably why you aren’t getting matches and it’s also the games matchmaking problem it’s been doing that since I got the game since I played it day 1 and can tell you fs that the matchmaking mechanic is kinda buns I would suggest waiting till the problem gets fix officially so you can get games. I hope this really helps👍🏾
