Why did site indexing decrease after switching to https?

Now in the tool for webmasters I added a site with https again. Will this be enough or do I need to do something else? Or is everything fine and Google just started indexing the https version? And the data for it will appear after a while? Yandex also does not show data for a non-https version (for example, search queries). For https, it says that there are no statistics. Do I need to do something with Yandex?

Answer 1

Naturally, the number of pages with the http protocol has fallen. Now they are indexed with the https protocol. Have you verified the version with https in Tools?

Answer 3

It is logical to look at the section with indexing errors, but you did a complete redirection of pages from http to https

Answer 4

I've read how people's sites are pouring in the search results after the transition, and I didn't want to switch to https :)
In the meantime, I already bought a certificate, and the site is already available in both versions. I sit and think, maybe 2 days have not passed yet to redirect from https to http?
