Game Center invites do not appear when our game is maximized/fullscreen; only when it's in Windowed mode. If you alt-tab out of fullscreen mode, there's no notification available on the desktop (like there would be if the game wasn't open at all) so the application is consuming it but not displaying it.
Is there something we need to do to get this to work properly?
For what it's worth:
- We're using the Unity game engine
- We're distributing the game via TestFlight
- The invites work just fine if you're not running the game and you use them to launch it.
- The invites work on iPhones/iPads
