I noticed that that after I 1) moved my P2 pedals from a bike with 175 crank length to 172.5, and 2) then went into Garmin sensor settings and changed the crank length from 175 to 172.5, that then when I 3) opened up the PowerTap app on my phone it indicated that the crank length for the left pedal was 172.5 and the crank length for the right was still unchanged at 175. So Garmin Edge 830 is not correctly changing the crank length on both pedals. Anyone else notice this?
