Minus sign in AdSense earnings
A couple of days ago I found weird minus earnings in AdSense. The numbers are weird and also the minus sign.
There doesn't seem to be much talk around this subject, only tens of people have reported this on Google Product Forums.
A couple of people have posted official answers from AdSense team that this is a bug of some sort and Google does not yet know the reason or source of it.
Both of these reply-s from support are stating that engineers are working and this is a system bug with the home tab.
Best of luck to Google engineers fixing the issue! As to the official reply-s all the AdSense publishers should remain unworried about their payments unless they have invalid activity on their account.
