Button not released message

[mjbok]

I took off and I got a "button not released" message on the controller screen. I rebooted the drone and it didn't come up again, but has anyone seen this before and does anyone know what it means?

I too got this message but could not find the cause. The message disappeared after I shut everything off. Autel should have a list of their messages somewhere for us to access.
