Can't add new spots in the mobile app

Version 3.1.1 (422) on Android.

When attempting to add a new spot, there is a ton of unwanted behaviour. Firstly, after setting the wanted location/coordinates of the spot, the app changes it into something else. Earlier I have had it switch the location (multiple times) to a random spot in Austria, and now I had it somewhere in Germany. Chaging the location back after this unwanted change, the location stays, but the ‘Save’ button is unresponsive.

Expected behaviour: firstly, the set location should stay the same as the one put in first. Secondly, the save button should not be unresponsive, and pressing it should result in a new spot added.

This means, that currently, at least for me, there is no way of adding new spots through the mobile app. This is most unfortunate, as the mobile app used to be a very handy tool used for the topoing process, ESPECIALLY setting the locations of the spots as you can match your own GPS coordinates.
