Development gives iOS app(.ipa file) to test. I am able to install the app to iOS devices(iPad 6th generation and iPhone Xr with iOS 13) using iTunes. After installation app is launching, but when i connect the device to internet, app not launching.
Tried few fixes
Settings > General > iPhone/iPad Storage > Uninstalled the app
Settings > iCloud > disabled iCloud backup and iCloud Drive
Tried re-installing the app, but issue continues.
I am using iTunes in Windows OS, as i don't have macOS hardware. Appreciate any help to solve the issue
