Update to IOS10 ruined it!

The only game I played before the update was Phase 10. I play it daily with friends and family, and since the Game Center is gone we cant. Paid for a game that is now useless. The invite friends with a iMessage works, sort of. However it will not let me ONLY select 1 friend or family member to play with. I send them the invite and it automatically adds 2 strangers or robots and makes it a 4 player game. I dont want that, plus they never take their turn! So frustrated!!!

Smarssy about Phase 10 Pro, v2.3.0
