Thanks for the quick reply!
I updated to 1.6.9 and just rebooted. Still got same issue, the location is still in a city 120 km away from me, just in a different street now... not in the middle of the lake anymore
I connected my laptop to my phone's hotspot (which uses the same home wifi) and the locations changed to different city 120 km the other direction from me, still wrong though. this is confusing if it locates my by my network's location is used, shouldn't it show the same location both times since it is the same wifi?
I also tried the eset anti-theft tool. Not sure what method they used for location, but it was almost right.
