Yale Assure battery level

I just upgraded to a new lock and new Vera. firmware 1.7.4001.The old system with Yale touchscreen UI5 worked perfectly for many years despite salt environment, then the Yale lock started to malfunction. The new interface looks better, but like others have noted in the past the battery level does not function. I have not upgraded firmware because it is at a rental house that I own and I don’t want to crash the system when I don’t have immediate access. Any suggestion very welcome. Chuck
