Then you can add it to the offline list and it will be displayed on the map.
But how else can this be resolved?
Each time the application is to check all descriptions, are there no coordinates saved in them?
Maybe some "Search waypoints in description" button?
On the other hand, it is probably a relatively rare situation when the waypoint is not added "officially", but only in the description.
a) taking five screenshots
b) editing files (pink frames and texts)
c) ezgif.com/maker + resize
d) uploading files to postimages.org
e) "insert an image" to post
