I have an enterprise app which is currently being used widely in my organisation however today some of my users received this error message when attempting to open the app "(app name) is no longer available".
I searched the internet trying to find relative information without any success, the closest i could find was that a provisional profile or certificate had expired, so i checked both and can confirm all of them are in date and valid.
Can anybody explain to me why this is happening and how i can solve it? short of re-installing on every device which is going to take a very long time.
