Bug: tracking home zone

Hi

Arter last update of iOS app i get the à major change of location have happend, when I check map im about 400 meter from my home. When i manualy update the location im home again. Happends about every 3h or if I manualy open the app.

What could be wrong?

À quick test, if i update location manualy i get home, then close app and open im back about 400m away from home

I did reinstall app, still same.
