No engine battery voltage information on the tablet or app

[Tycoon]

Hi All,

First post here
Just got the beach camper and I realized, unlike in many videos I’ve seen, my tablet/app don’t show the engine battery voltage.
Note that it sometimes randomly shows some moving numbers but most of the time it’s blank.
The current charge in % is shown though. Only the second battery shows the „charging“ symbol on it.

I wonder, is this normal?

Thanks in advance

No idea, but will want to see, what somebody recommends.
Going to be a learning curve with the T7, that’s for sure.
