Why does Yandex not display pages with the "Canonical" status in the search?

Question

Yandex

In "Yandex Webmaster", in the "Monitoring important pages" section, the main page has the status: in search , all other pages have the status: non-canonical after several crawls.
In Yandex search, upon request, it site:domain.rudisplays one single main page. In "Google" for a similar request, all pages are displayed in the search.
Why hasn't Yandex displayed these pages yet?

Answer 1

Did you check the canonical tag in the code on the pages?
From all non-main pages, as I assume, it directs you to the main one. Accordingly, you need to remove this tag on all pages, and the site will be indexed.
