I have a samsung galaxy ace with airdroid v3.0.4.1 and when I open a browser on my win 10 pc to to use airdroid some contacts are duplicated in the contacts list in the browser. If I then look at the contacts using my phone there's no duplication. This happens with both google chrome and MS edge. Is this some kind of bug because it's really annoying and the duplication is random. I'm not syncing with my google account, I have no facebook account, this is purely a sync between my phone and the pc. Thanks for any advice.
