That is what I am saying in this thread:
I recently had to help a friend who I have installed /e/OS on her phone. She wanted to share a location, not her location at the time, with the Magic Earth app.
When I finally find how to do it there is a big problem: the person receiving it either has that app installed (and the link opens in it, of course) or receives a web link that simply tells them to install the app.
So I installed another one from F-droid, specifically Organic Maps. Here it does share correctly: it sends a link that the receiver can view as an OSM web map. And there appears a button to ‘view in app’ in case you have it installed.
This kind of issues are very important, because they give the impression that the system is closed (only people with the same system can understand each other) and people who come from Gmaps are used to everything is simple and easy, causing the rejection that we Linux users recognize.
I hope you find it useful if you have the same problem.
