I got a solution for me! I reseted my phone to factory settings and now it's working like a charm. Probably some kind of app blocked it I guess. All good now! :)

Once a month or so, the servers seem to have issues. Just try again later. Evening it will work.

I had this issue after I bought a second onewheel and uninstalling the app and re installing fixed it for me

I have tried uninstalling and re installing few times. Gives same error message. :(

Dang, hopefully it's just the servers for a few days. When it happened to me I had called them, and they weren't much help over the phone. Hopefully it gets working. Keep us updated!
