I have a developer account yet installing apps such as Instagram++ are only running for 7 days and then I have to install the app again using Impactor. This is only happening on my 8+. Installing apps on my 7+ and 6S+ using impactor last for a year using my developer account. The difference on my 8+ is when installing an app, it skips right past me selecting my user name for developer account and goes right into installing the app. Anyone have any ideas on why only my 8+ is not signing apps longer then 7 days? All my phones are on 11.3.1.
