@bjoern-0 same issue here with the new app version. Every day, I receive two different Android notifications. One is for my actual location and and the other is for my same longitude but a completely different latitude, nearer the equator.

A week ago I was on holiday in Austria when I first saw it. Selecting the 'false' notification would always give me a point roughly in the Saharan desert. Now I'm back home (UK) and it gives me a point that is -1.36° (S) and -1.36° (W). My actual longitude is 1.36W, but I'm very much in the +50°N latitudes in the UK.

Here's the 'false' notification top, and the correct notification (for my location) at the bottom:

Here's what I see when I tap the false notification. Definitely not my GPS location:
