A station is wrong or missing
Station lists are generated from the operator's open timetable feed, so a change at the operator reaches the app after the weekly refresh. If something looks wrong, email the city, the line and the station and it gets checked against the feed.
Restoring Pro
Pro is a one-time purchase tied to your Apple ID. On a new phone, open any Pro feature and tap Restore purchases. Refunds go through Apple at reportaproblem.apple.com.
Nearest station finds nothing
It only knows the cities in the app. Outside them it shows the distance to the closest one that is included. Location is read once, in the foreground, and never leaves the phone.
The widget is empty
Open a line in the app and tap Pin to widget. The widget shows that one line until you pin another.
Requesting a city
If the operator publishes an open GTFS feed, it can usually be added. Email the city name.
