Suh dudes, I have recently acquired a BG-R10 for the vertical shooting functions on my R6 Mark II, and have run into this error in the attached picture. I have OEM LP-E6NH batteries and have tried cleaning the contact points with a dry cloth and eraser. The battery still works fine when installed directly into the camera, but displays this error when I try using it while installed. Would appreciate any advice from anyone who has run into this issue!
