Zero Offsetting P1 pedals using just Rouvy android mobile app I don't have a bike computer, rather I use my old cellphone for that matter. Does anybody know how to do a zero offset of P1S pedals using Rouvy app? Apparently, there should be an option when you pair your sensor, but on my app I don't have one. Please see the attachment and thanks.
Here is what I was received from Rouvy help desk: 

"The problem is that this feature is not available on Android. But, you can use any desktop app and just Zero offset your pedals and then use your phone for a ride."
