@kogi_rc and @ycode thank you so much for your help with this. I never could’ve figured out how to get past this on my own lol.
@ycode @camillazi - I got it working in 2022.3.11.f1 with your steps above, but I also had to go into Edit > project settings > Apple Build Settings and change the minimum ios version to 14.0.
thanks to this comment for the 14.0 fix: GKLocalPlayer.Local.FetchItems() Error on Unity - #15 by AndreaMar
I haven’t actually built with any of my code that uses the plugins atm, but these threads at least got my app up and running with the packages in it. I really hope Apple gets the issue fixed officially soon.
