Default JB4 App new user question - 08-28-2021, 01:56 PM

I just bought a used JB4 from C450 owner. I would like to know should I use his login to check the firmware update the very first time after I installed my JB4 to my C450? or I can just register/create a new login(my own). After connect the App through the Bluetooth to the JB4 unit, I can check and latest firmware update myself, right?

I just want to know if the previous owner's App account will have any connection with the JB4 unit which might create any conflict with my C450?

Any help and advise is appreciated. Thank you.
