Tester who are using IOS 11.4.1 are unable to run the test builds on their devices, This didn't happen before, after installing the build from beta app this happens download problem detected :(
But the application installs on my Device which is also using IOS 11.4.1.
These are the steps i tried for fixing this issue:
1) I checked all the UDIDs (all of the UDIDs were in provisioning profile already)
2) Removed XCode cache, made new build but still same issue
3) Updated the crashlytics to latest version
4) deleted provisioning certificate from apple website and made a new one.
basically followed these Questions but wasn't able to fix this
