Reporting a problem, and My reports

Tap the small lifeline mark in the top bar, beside the bell, on any screen. Choose Something is broken or Something could be better, write what you saw, and optionally attach a screenshot. It goes straight to Andreas, a person, with the screen you were on, your app version and where you are in your plan, and the sheet tells you that before you send.

Profile → My reports shows what you have told us and what happened to it: received, being fixed, fixed, or not planned. When a fix is ready you get an email that links to the same page, where you can answer Did that fix it for you?. If it did not, it goes back to Andreas to look again.
