Hreflang has non 200 URLs filter showed pages in “head” section of which there were links to pages with harmful 4XX-5XX Status Codes
Hreflang has non-indexable URLs filter showed pages in the “head” section of which there were links to blocked URLs.
4. The list of pages with each bug was downloaded to implement all the needed fixes:

The result of these actions is positively impressive: the number of indexed pages has increased by 7% after 2 weeks and it keeps increasing.
