'App can't display over other apps' error

If you're having difficulties with granting this permission, we've found a YouTube video that should be able to help you with that:

"Special app access" may be found under a three-dotted menu on the App page, rather than being listed like in the video.
"Display over other apps" may also be written as "Appear on top".

You could also try to close down other, unnecessary apps as this should help the process.

If you're using Android with operating system 15, please refer to this article.
