Multiplayer game advice

Hi all
I am really confused about how to introduce multi-player to my cards game. Would you suggest I go with the Google play game services or should I use some online/cloud service? I heard about appwrap

What do you suggest? I find play service is free but limited. While appwrap cost money but give you a lot of control.

I need you advice

No one knows?

Google Play Game Services is an online/cloud service. What exactly are the limitations you see?

You can’t list rooms. Also once you join a room, you can’t leave and come back if you got disconnected or even have someone else take your spot.
