I updated my signature today and now on my yobit account under
Amount BTC I am getting zero. Anyone else having this issue?

I have the same result. And I do not think we have the option of getting our payment back for these posts.

After updating the signatures there were many errors in calculating posts so that the balance was not added to the yobit panel. Maybe it's a system error and the yobit admin doesn't know so he hasn't fixed it yet.
To be honest, I haven't updated my signature and want to know the notification from Yahoo directly.
