I am having issues upgrading my lock to my U-Bolt Pro Wifi lock from firmware 1.21.0023 to 1.22.0023. I haven’t been able to update it for while. I have tried to factory reset the lock, but that did not resolve my issue. I have tried over bluetooth and wifi with no luck.
An additional note, I takes me multiple time factory resets with the reset button before I can get it to link with my phone to do the initial setup. Not sure if it is related, but it can be difficult to setup after a reset.
