On Monday, I had a major decrease in the people who bought my app via in app purchase. Normally, this would be a very rare result, an outlier that happens once in a blue moon. But I got the same result on Tuesday, and while Wednesday was better, I've noticed the overall rate at which people purchase the app per download has suddenly decreased significantly. It had been about a week since my most recent update and the app had been working fine. Since the decline, I've had no no complaints from the users about the app's functionality.
I've really combed through the numbers and tested my app on all devices (except for the new full screen devices, but I'm going to buy one today) but have been unable to find the cause. I am wondering if anyone is experiencing similar issues? My only hope is that this has some thing to do with iOS12.3 and a change to StoreKit possibly as I noticed Monday was the date when 12.3 users started to pick up. Otherwise I'm completely lost as to what exactly is going on here. Any insight would be appreciated!
