Pressing the mode button to switch between charging protocols (e.g., normal, Lithium, etc) no longer works. I am able to switch between charging protocols using the VictronConnect app. I just checked and my firmware is up-to-date. I have tried power cycling, trying the mode button with the batteries connected or disconnected, holding down the button. The mode button simply no longer does anything. I have searched this user community but nothing similar came up. Had anyone encountered/seen this issue and if so, is there an easy fix, or might this functionality of my charger be truly broken?
