Our users from Australia reported that there is Audio Sound coming from a mobile banner ads, and when that happens the mobile banner ads will disappear. This only happens in Australia, we have tested many other countries and we can not reproduce this. However, we do not have testing devices running in Australia. The Audio is about 1 minute long, and two male talk about treatment for cold symptoms such as nasal congestion and throat discomfort. I am wondering if anyone else has this issue? Thanks in advance.
