After I distributed an app created with an enterprise license to an iPad, it started up normally and worked the first time, but after using it for a while, it stopped working. When I tap the APP icon, the message below appears even though the iPad is able to communicate with the network. If there is any solution, please let me know. Unable to Verify App An Internet connection is required to verify trust of the developer "iPhone Distribution: XXXXX Corporation". This app will not be available until verfied.
