Non-visible but clickable banners on Unity
For Unity versions 5.6.0 and 5.6.1, banners are not visible on some Android and iOS devices, however they are still rendered and clickable.
For users on the Unity 5.6.1, the issue can be solved with the following patch: https://unity3d.com/unity/qa/patch-releases/5.6.1p4.
We suggest users on version 5.6.0 to update to version 5.6.1 since the changes are minimal.
