Stat issues (since last update)

Since the beginning of this month (somewhere) my stats dropped like crazy. Of course there is always some fluctuations, but never before I had it drop this much (50% to 60%).
I read somewhere that it might have to do with AMP… Is that the case? If yes, any idea when this will be solved? Those extremely low numbers are stressing me out…!

With the previous update my stats were down for about three days. This time it’s way longer.

Thanks in advance.
