When selecting the second app for a split screen setup on iPad, VoiceOver does not tell you if an app you're selecting does not in fact support multi-tasking
After selecting the split screen option in the multi-tasking menu, you are returned to your Home Screen to select the app you want to share the screen with. Some apps are not supported, and if selected will simply open in full screen, but VoiceOver gives no indication of which apps are and are not supported.
Steps to reproduce
Open an app which supports multi-tasking, for example Safari.
Go to the status bar and open the multi-tasking menu, and select the Split Screen option.
You will be presented with your Home Screen, from where you select the app you wish to add to a split screen setup.
Some apps are not supported, but you are not warned or prevented from selecting them with VoiceOver.
The new app simply opens in full screen if selected.
