I have a BMV712 battery monitor installed in my camper. Until a few weeks ago, I was shown a historical trend line (approx. 30 days of recording) in the VictronConnect App (Bluetooth-Connection) under Trends. Now I suddenly only see the live trend and no longer a historical trend line. Is this a known problem? What can I do to get the historical, recorded trend line displayed again? Was this feature deleted with the last firmware update? I would be very grateful for your help.
