How can I get rid of "Update to recommended settings" warning?

Question

I'm porting an iOS game to tvOS (Unity game). I have this annoying warning that I can't get rid of. Whenever I click on "Update to recommended settings" it pops up a window saying "Project settings are valid". The warning's still there.

(Never mind the other warnings :D)

Things I've tried: Clean>Rebuild the project, restart Xcode

Any ideas?

Answer 1

I found that closing the project, quitting Xcode, restarting Xcode and re-opening the project worked for me. Xcode 8.1 (8B62)
