We have a support ticket with publisher support, but was also recommended to write here. Our ticket number is 6-0131000030757.
In end of October we started receiving user feedbacks regarding our app randomly crashing/freezing/causing performance issues and ads playing sounds even when the device is muted. This exalted quickly and we have now toggled off ads in our app.
We are seeing this issue on multiple devices, booth iOS 14 and iOS 13 and on multiple versions on our app, even old versions.
I August we had a similar issue where we found one ad that used all the available CPU and GPU causing phones to overheat. In that case we where able to identify the ad and block it. We may think this is a similar issue.
For the short-term, is there anything we can do to identify which ad is causing these issues? We have not received the ads ourself.
For the long-term, how can we stop these ads being delivered in the first place? It's not a valid solution to always try to find the ads causing the issue and block them.
