After upgrading an auctioned ES4 with a replacement dashboard, the scooter works and connects to the app but it will not switch modes when you double-tap the button.
Doing so just toggles the light, and whenever you turn on the light it activates the speed limit!
It does not however alter the LCD display which always shows the red-S indicating sport mode whether the speed is limited or not.
FYI the default functionality is a single-tap activates the light and a double-tap changes modes from Limit-mode (no S), regular-mode (blue S) and sport-mode (red S)
So now if anyone wants to use the scooter they cannot activate the light or it will cut the max speed in half.
Any idea how to fix this? Firmware has already been updated to latest.
