friends not showing online

This started 2 days ago. my friends and i were playing pga tour the night before. and poof out of no were we all cant see each other online nor send game invites to each other. i dont get it billion dollar company and they cant get a simple app to work 😡😡. Does anyone else have this issue or a way to fix it. i have tried clering the cache and logging out and back in i even blocked them and unblocked them and still nothing.
