Tried reinstalling but still won’t let me spectate friends while we have not change settings… Need it for quest and fun with friends please need help.
The section on “challenge a friend” also applies to spectating:
Unable to challenge a friend on mobile?
If you are unable to duel a friend from your friends list, you will need to wait until both players are on the same patch.
So, just wait until the patch is available across all platforms. Should not take more than a couple of days.
