I have downloaded the mobile app and tested it today.
It’s a useful tool but there is one issue that bugs me.
I like to appreciate my ride-ons with a wave but while all buttons seem to be working, the wave and the elbow seem to be working only sporadically.
Also, I missed the junctions as I was unable to switch direction, where are the buttons for that?
I use an Iphone5s and wonder why it is not working well.
