Yandex adverts are not showing without force reloading the page

Good afternoon. I tried to put home ads from yandex. Everything works fine when you go in for the first time. But when you leave the first page and go somewhere else, the ads just stop working.

Only forced reboot on mobile device helps, or on computer only ctrl+f5 helps. I saw a similar topic, but it went unanswered. It’s been almost 5 years since that thread, maybe something has changed and I’m doing something wrong?

I added content security policy script src everything that is necessary, based on the recommendations of the advertising platform yandex.

The video clearly shows that the adverts are working, but as soon as I start surfing the pages they don’t appear anymore.

PS also in the console I have a lot of errors.

I will be very happy to get any answers. Thank you.
