How I can change the content restrictions settings?

I live in Russia and use the social network VK.com

Recently I switched from the Android operating system to the iOS and faced the problems of displaying content on the above social network. In some public pages I see this announcement: "The community probably contains inappropriate content and is not viewable", BUT this page does not contain any prohibited content and opens freely on devices with a different operating system (an example of this situation is shown below). By the way, this public page is about art and this situation happened more than once.

I tried to find something that could fix the situation in the settings, but I didn't find anything (screen time settings didn't help either).

By the way, I have already reached the age when I can also watch adult content and I really don't understand how to solve this absurd situation.

This greatly interferes with my work, because some of the pages I work with may not be displayed in the search for reasons I don't understand.
