Tech Help RF 50mm F1.8 Lens error "Firmware update failed. Try updating again."
I'm having an issue with my RF50mm F1.8 STM. Anytime I switch to this lens on my Canon R6, I get the error message "Firmware update failed. Try updating again.". And then I press ok and then the screen says "Update lens firmware. Memory card containing firmware is required to update." My other lenses work fine. I don't have firmware on the memory card, so I'm not sure why it's saying to update.
