Warning: iOS 14.2 and 14.3 Compatibility Issues when using an MDM Solution - Fixed in iOS 14.4
Due to an iOS compatibility issue on some iPhone and iPad models with iOS version 14.2 and 14.3, the Glink for iOS apps are not able to start if managed by mobile device management software (MDM). However, if you run Glink, Glink 5250, Glink 3270 or Glink VT for iOS after a normal download from Apple’s App Store, Glink works fine.
If you are using an MDM solution, we recommend not to use iOS 14.2 or iOS 14.3 on your devices, Stay on iOS 14.1 or go straight to iOS 14.4 or later.
