My foot switch G works fine but. When used to “dial “in a particular parameter it turns but nothing happens. Perpetual spin. No hard or heavy hit was ever applied. Just stopped working.
You can try to backup and then factory reset and restore. Otherwise email email@example.com so they can log the issue and coordinate repairs if needed.
Have you confirmed that encoder G is assigned to a parameter in that particular block’s edit screen-is the LED for encoder G illuminated? If so, have you tried it with more than one block to see if it is non-functional in every block?
