Hello, I created a simple AR app in Unity and built it on my iPhone using XCode. But after approx. one week the app stopped working (when I click on the icon it opens for a millisecond and quits). This is not a bug because after I build it again it works perfectly one more week and then stops working again. - Do I understand right that it happens because I use "personal team" in Xcode and a free "Apple Developer program"? - Do I need a paid version of the "Apple Developer program" ($99) in order to make my apps work with no time limitations? Thank you very much in advance!
