Insertion not getting disabled on mobile devices

The wrapping code is generated by Ad Inserter – you can have a simple div with custom CSS:

The url given does not cover a scenario for a popup code.

You can use wrapping div with any ad code.

Wrapping div needs no style, it is needed only for classes in order to identify blocks for client-side detection.

I tried, and then the code fails to activate.

Can we have a sample settings screenshot for a popup code that is inserted into the footer – and shows only on desktop?

Make sure your code supports asynchronous loading.

Please enable remote debugging so we can check plugin settings and your code.
