The location row inside feed options on Things To Do chooses where onto looks. my location uses your location once to choose where the feed searches; it is never saved or sent to the event catalog. choose location lets you pick a spot on a map instead, and the pin is forgotten when onto closes. change city opens the available cities. Choosing one changes the feed and is remembered when you reopen onto. You can return to your position with my location.
If a location fix is unavailable or outside supported regions, choose a place on the map or an available city. Map providers receive the area you view; your pin stays in memory. You can allow location in system settings, then tap my location again.
