There are still some streaming apps that don’t properly support the multi-window mode in Android 7.0. They stop video playback as soon as the other window is selected. The Teleboy Live TV app is a good example of this. It means you can’t watch TV in the background while doing something else in another app.
For the next App Cloner update I’ve added an option ‘Multi-window no pause’, which works specifically for the Android 7.0 multi-window mode by preventing the app from entering the paused state while the multi-window mode is active.
So you can watch two Teleboy Live TV instances simultaneously 🙂
