Could you post a screenshot of your settings so I can try to reproduce?
Thanks!
Thanks! These settings appear to be correct.
Do you use a caching plugin or service on your site? If so, could you make sure that cache is flushed for all mobile devices?
Let me know if it helps.
No caching on the site and no caching service.
Unfortunately no change.
Could you try to switch to one of the default themes, like Twenty Thirteen, for a few minutes, and let me know if it helps?
I switched to Twenty Fifteen and the empty ad box (or grey band, depending on what you want to call it) was gone from the bottom of the site. Switching back to my normal theme had the empty ad box appear again.
That’s odd. Even after you switched themes and then back, I still see several references to your theme when looking at your site on Mobile.
Do you happen to use a plugin that extends your theme, or that was delivered with your theme? If so, what happens when you deactivate it?
