Hi - Does anyone know why my show rate of ads using Admob has dropped since February 2021? If you look at the attached I was getting low requests from July 2020 to Jan 2021, with show rates of 25-60%. Thats not great, but from Feb 2021 the show rates have dropped to 0.15%-0.25%. My ad requests in this period have increased from around 100 to several thousand, but the impressions are lower now than they were previously. If anyone has a reason for this please share? Note I have largely not touched anything on these games or my IOS account in the last 9 months.
