I have the our device connected , with Assistive Touch enabled and the application running in the foreground. At this point, I place the screen on standby and leave the device unattended for 10 minutes. After this period, I return, unlock the screen, and observe that our app is still running, and the connection with the device is re-initiated. However, something occurs at this stage that causes the application to briefly switch to the background and then immediately return to the foreground.

This behavior leads to system instability. Ideally, once the application is running in the foreground, it should not transition to the background automatically. However, it seems to be doing so for a short duration—momentarily switching from the foreground to the background, then back to the foreground—which is causing the observed instability.

OK, the iPad screen is unlocked AND App Appears.

Suddenly the application goes to background by itself?!?!?!
