Just upgraded our RV batteries from AGM to lithium and a new iphone 12 pro. Went to the Victron App to change the settings. I can see the Victron Controller (mppt 75/15)but when I select it, it asks for my pin. I haven't changed it, still six 000000, but the pin isn't accepted and after three or four attempts it just refers me to the owner's manual. I have deleted the app and reinstalled it. Each time when I open it, it recognizes my controller but won't pair.
