i’ve noticed that if you manually input coordinates / positional accuracy on the observation edit screen and immediately click save, it doesn’t always keep the information. on that screen, you have to move to a different input box before you click save, i think… or something like that. whatever that process is, i always double-check after saving to make sure coordinates and positional accuracy have been saved appropriately.
if you input that information on the upload screen, generally i encounter fewer unexpected issues there. the only thing that sometimes trips me up is that if i’m editing multiple observations at once, i need to make sure to begin the edits using the left pane, not the observation cards.
EDIT: i just tried messing around with the observation edit screen, and i can’t reproduce the problem that i’ve seen in the past. so it’s possible that the problem has been fixed, although data affected in the past will still be bad.
