Hello, we have dating app, it is basically 2 years old. About 3 months back we hit 1 million downloads in 1 and half years. Now app have 1 300 000+ downloads. We are working basically all time on same ASO and same keywords. So after new years our app rank started to drop and registrations as well. Before 2017 new years we had 1400-1800 registrations in day. So after new years we had only 700-900 registrations. So we made new nice screens for phones, for 7-10 inch tablets and our installs raised a lot. In 2017 April we got 230 000+ new installs, we got back our rankings and registrations. So google play made new update on this month 1 day. 2017 May 1 we got only 683 active installs, day back it whose 4000+ and another day back 7000+. So ranks and installs just basically disappeared. Now we are getting 200-250+ registrations in day. We talked with one guy, he said it maybe "dance" and if we will not get back our rankings in 48 hours we need to do something. We contacted google play as well, they investigating this thing, and we got one email from them whit question: when your rank dropped? So anybody maybe have some opinion on this? How this can happen, old nice ranking app just goes down suddenly from nothing.
