I started an activity on maps, how do I make the marker appear on the map normally without looking for my activity?
I'd love to help you with your problem, but I need more detail about the application you are using and what you are trying to do.

First, there are many applications across a variety of platforms that provide map information and track activities, such as Google Maps, Apple Maps, Garmin, or AllTrails. It would be helpful to know what application you are trying to use and on what platform (iOS, Android, web).

Second, what are you trying to achieve? You mention wanting to see a marker on the map. Do you just want your current location to be marked, are you trying to plan a route, or are you trying to do something else?

If you are able to provide any additional details, I'd love to try to help.
Sorry about that. I'm using the Android 13.0 Maps app.
In this case you are most likely talking about Google Maps.
Can you specify what exactly you are trying to achieve?
