So yesterday I had a sudden spike in downloads from China for one of my apps, kinda weird, because it usually never gets downloaded in China, maybe only 1-2 times a day. However, yesterday it was downloaded more than 4.500 times. To make it even more weird, according to my Firebase console, there were never any sessions from China yesterday, so the app was never opened?! Ranking and keywords were the same according to App Annie, so no change there either
Any idea what is going on?
