Has anyone had this issue? You have to hold the buttons down to go to the menu but then it goes to feed mode automatically and that screen doesn’t flash.
Things I'd try:
1. Disconnect/reconnect the Display module.
2. Update the Display module software
3. Reboot the Apex.
If those actions don't fix it, then it's possible a button is stuck or it has circuitry damage. You'd likely need to contact Neptune Support, or try fixreef.com.
