Android App Instructions

Can anyone point me towards any Android App instructions, like what all the buttons do, for example.

This link should help you out: https://support.zwift.com/hc/en-us/articles/205055065-Zwift-Mobile-Link?section=200993429

 And this: https://community.zwift.com/news/2369-zwift-mobile-link-say-hello-to-a-new-map-and-messaging-feature

 

Still can’t see any instructions or explanation for each of the buttons at the bottom of the Android mobile link…
