Scooter locks up and demands reception

Hello, I drive a niu 1s. Today I got it. After unpacking I drove 100 meters and that was great. But then problems occurred after I loaded it. The app signaled to me that the connection to the scooter is closed for an hour and demands a location with good reception. In my coffee there is no good reception. In the meantime, this has turned up to three hours lock. I don’t even dare to watch how many hours it has been in the meantime Is there a way to separate the scooter from the app, and then continue driving or even driving? Or do I get so far from any setting that I can drive? I suspect that the scooter has gone into some theft mode. For help I would be very grateful. The error code is by the way 161
