We have an app that was distributed using Enterprise Distribution Profile. Now, the same app is working for some but others are reporting the following issues.Existing/Installed app throws this error, and doesn't open: "{App Name} Is No Longer Available"Users who try to download the app from the Enterprise link are reporting this error: "Unable to Download App - {App Name} could not be installed at this time. [Done][Retry]"Users running iOS 8.4.1 are specifically reporting these issues. I regenerated the profile and rebuild the app. This seems to have fixed the issue for some users, but not for all. Note: The profile did not expire.What's the real problem here? Thoughts?
