Seems like my previous post got lost in the ether, so if this double-posts, my apologies.
On Androind 7.0 devices, AdMob banner ads that worked in previous OS versions are now displaying on the top left corner of the app. You can even see this by downloading Tappy Chicken on the Play Store using a 7.0 device. This issue is not present on Android 7.1.1, but since carriers are rolling out 7.0 without any dates for 7.1.1 this leaves a large enough gap for 7.0 users to experience this issue.
I have an AnswerHub post here, but unfortunately it has seen no traction. If anyone has any information/ideas on a fix or workaround, I’d greatly appreciate it. Thanks and have a wonderful day!
