I have submitted iOS app to TestFlight and when my internal testers try to download app it says the provisioning profile is invalid. I have verified that the provisioning profile is not invalid. Is there something else that could be causing this.
I am using Xamarin on windows. I was able to successfully submit a different app to TestFlight using same certificate and app id.
Basically what i am looking for is a way to troubleshoot this other than just looking at the status of profile on the app store.
