When I export my android game using "advanced minification",the game hangs on the loading screen. Hence I use simple minification. If you use simple minification then maybe your problem may get solved.
I was hitting this bug too. Have been freaking out for the past couple hours because I pushed an update through to all of my users (all 10 of them). This fixed it! Thank you so much!
Hopefully the mighty Construct team can fix this ASAP.
Ashley I also want to note that this is not just an issue on iOS but Android too. The app opens but then gets stuck on a "0%" loading screen (on export with advanced minification).
