Ads do not appear in Facebook browser

Hello, I would like help:
The plugin is with 2 adsense ads active within the posts, one at the beginning of the publication and another at the end. But there are instabilities in Facebook’s native browser for mobile devices. Sometimes it opens all the ads, sometimes it only opens one, sometimes none. When someone does not open, only the empty space of the ad appears, and sometimes the text of the post goes on, with no space at all.

In google chrome it works normally, it’s only in the Facebook browser.

I would like support.

Hugs.
