Did all the troubleshooting steps. No luck, reset to factory, still won’t rotate.
Can you move it by hand? If not, something is jammed in there, if so, the bottom motor has probably died. If within the 1 year warranty period, contact support and get it replaced.
If you have it mounted upside down outside, I’d recommend against doing that with the new one, unless you build something to cover the bottom. Water and dirt can get in when upside down and cause all kinds of issues.
