@boristheblade: Does the desktop start if you connect the Pi to a screen via HMDI before booting? If Jivelite’s autostart is activated, it starts automatically after booting. So you probably won’t see the „Start Jivelite“ button, but instead you should see a „Stop Jivelite“ button.
@s21 Which Max2Play version is running on your Pi 2? Have you already updated the image to the latest version? Do you have the opportunity to test Max2Play with a Pi 3B to rule out that our image has problems with the Pi 2?
