I did the update to 3.11 before I saw the “don’t” comments.
However, the issue was already there in 3.10 let alone 3.11
I haven’t tested, but I’ve read that if you still have the previous firmware .BIN files, you can just load back into the camera, effectively “rolling back” the updates.
I won’t bother if the issue is just to do with lens calibration.....z lenses don’t seem to need it.
