Background Functionality Doesn't Work at All

[hakarune]

Does not track in the background at all. I set it up on my phone and let it run for 2 days and it never updated my location. Had 2 other devices join the group and they didn't update in the background either. GPS only tracked and updated in foreground and after about 3 hours the phones with it running in the background disappeared off the map entirely until I reopened the app.

As it stands, this is not functional for the intended purpose.
