At the moment the Kompass map is no longer working. I will attempt to find a way to get it to work again, but it’s entirely possible that won’t be successful.
As with all free maps, I can’t make any guarantees that a given map will remain available, as the map owners may stop providing it or start protecting it effectively.
The owner of GPSies sold their web site to AllTrails, which subsequently closed the APIs that MyTrails was using to upload and download tracks. I will remove the integration in a later version of MyTrails, but for now MyTrails will just display an error when you try to use GPSies.
I’m assured that MyTrails.com.au is still operational and has no plans to shut down or sell out. Feel free to use it for all your track sharing needs (uploading and downloading).
(note that despite the fact that My Trails the web site and MyTrails the app share a name and a good working relationship, they are operated independently – if you need support for the app, use mytrails.app; if you need support for the site, use mytrails.com.au)
OpenStreetMaps recently changed their server infrastructure to better handle the load. This had the side-affect of breaking all OSM-based maps in MyTrails because they now require a specific per-app User-Agent HTTP header.
Unfortunately MyTrails didn’t support directly editing the HTTP header so fixing the maps required updating the app.
The maps should be updated when you launch MyTrails after the update, unless you already changed an affected map, in which case MyTrails will create a fixed copy at the end of the list.
