Unable to invite friends.

[laws_XBL]

I’ve reset my Xbox Series X multiple times.

My Show 21 is fully up to date.

I’ve reset my modem and network multiple times.

My NAT is set to open.

I’ve checked my Xbox friends list and it is online and working properly.

I checked my MLB the show 21 friends list and I only have about 1/10th of my friends listed.

I’ve attempted to “add” my friends in the Show 21 “requests” section and it “finds” them but will not let me invite them to game, only to party chat.

Does anybody have a sure fire way to fix this issue?
