I am a fairly new 2019 Millie owner and brand new to pantos. I placed this message on Face Book but have not gotten an answer so before I call service to help me work this out, here is my problem. My Millie turns on and from the front the SR works as it should. From the back, I have to hit the button several times before I hear the SR beep and can move the machine. Before I start fiddling around with anything, I was hoping someone can lead me in the right direction.
