I'm also experimenting this. There's no error message but the app icon is present. If I try to open it I'm having an error message: https://developer.apple.com/forums/thread/721474?page=1#739052022 Also related to https://developer.apple.com/forums/thread/720033?page=2

I'm also having this issue now. Haven't found a workaround yet... I have created a new build but now it won't install and I don't have any error messages. I have updated my certificates/profiles a few days ago, maybe it's related? I had been able to do a successful Test Flight build right after, but not anymore...
