So before I did the update I remember the pop up every time you start up everything and the calibration button was available. Well now the problem I'm having is when everything is turned on the pop up doesn't always come up anymore, so what I do is toggle the mini switch 10 times to enter calibration mode. I can't find the function that offers the calibration buttonSounds retarded but I have clicked on every button on the screen and can't find it.
