In early versions of iOS 12, the Proxyclick iPad app is going to sleep when the following iOS settings are activated:
- Auto-Lock is set to “Never” in Settings > Display & Brightness
- iOS Guided Access mode is enabled
This issue has been fixed by Apple in their iOS 12.1.1 release. There is a new setting under Guided Access, “Mirror Display Auto-Lock” which, if enabled, will have Guided Access mode respect the Auto-Lock settings.
