I got my Insta360 one yesterday and I just got confirmation that it is broken. It’s the Bluetooth that’s wrong and it can’t be fixed by remote. The error search was made by the app LightBlue.
I bought it at EBay and now it will be interesting to see, when and how I will get a new one.
I will update it continuously.
Update: I got the camera from the supplier and then I sent it back. It took some time but the problem was solved.
