Since Oct 29th, across all 4 of my established live apps (Android) I've noticed a massive dip in sessions/unique players in the dashboard analytics.

My inmobi requests/revenues are consistant with previous weeks, and my number of installs seems to be growing at the same pace it always has, so it doesn't look like my apps are being played any less.

So has something changed in the way Ansca capture this data, or is something failing, has anyone else noticed this problem?

Yes, same here.

Yeah, I can confirm the same pattern.

Taking one of my apps as an example, I was having around 200-300 sessions/day up until oct 29, then starting October 30 it has around 20-30 sessions/day... seems suspicious.
