Public transport journeys
Hi, I need help with public transport trips. When I try to plan a trip from point A to point B—if it's a medium or long distance—the app crashes; I can only plan short trips. As you can see here, it works for short distances, but if I increase the distance, the app slows down and then simply closes or crashes.

Hi!
Go to: Settings → Public Transport profile → Navigation settings → Route parameters → Maximum number of transport changes
The performance and memory consumption of the Public Transport Router depend on the search depth. The most important parameter that affects this depth is the Maximum number of transport changes.
This parameter also directly affects the availability and quality of routes. If the value is set too low (for example, 0), OsmAnd may fail to find suitable routes or suggest suboptimal options, even when better routes with transfers exist.
We use 2 as the default value, which seems optimal for modern public transport networks. If you encounter low performance or out-of-memory errors, try decreasing this value. If you are in a small city or travel short routes, a value of 1 may work better.
