Google Ads

Google ads are not always shown when browsing my site via PC. Via mobile browser they work just fine. The ads are not blocked in browsers. When going from Facebook to site post, ads show just fine. The problem occurred just after I updated the latest GADWP.

Examples:

This page does not show ads just before article and just after article https://www.kansalainen.fi/bosniaan-on-saapunut-tana-vuonna-jo-21-000-laitonta-siirtolaista/

Then this older page does show ads just before article and just after article https://www.kansalainen.fi/dusseldorfin-rheinbad-maauimalassa-edelleen-vakavaa-hairiokayttaytymista-henkilollisyystodistuspakosta-huolimatta/

However, if I go to the first page from Facebook, the ads show correctly.

Why the ads show correctly, if I go to a page from Facebook, but not, if I go directly to the internet page?

And as said, the problem seems to occur only in PC, not mobile.
