Question about SoFlow SO4 Pro

I have exactly the same problem. New tail light incl. cable and disconnecting the plug did not help. I suspect that the switch itself is defective. Has your problem been solved?
If so, how?

Hello, your scooter has a cover at the bottom front, there are various cables, disconnect the cables for 5 minutes. Greetings

Hello

Could the problem be solved ?

I have the same problem since today.
