User Notes
This version was only very briefly available in the app according to several accounts.
It likely had an issue and was quickly pulled before Ninebot ESX DRV 1.4.7 was released, likely in a similar manner to the Ninebot Max's BMS 1.5.3 and BMS 1.5.5.
There is also a DRV 1.4.5 for Ninebot Max.
