Has Google partially processed sitemap.xml files?

Question

Google

I ran into a problem, there is a sitemap.xml, which in turn contains links to sitemap1.xml, sitemap2.xml, sitemap3.xml, sitemap4.xml. All sitemaps are written in the same way, Yandex accepts them normally, but Google partially does not. I note that Google understands the nesting of other sitemaps in sitemap.xml, but only sitemap2.xml is processed by it, the rest does not want to. What I have not tried, and split the files into smaller ones, and write in * .txt format, and wait a few days. I also thought that some links contain Cyrillic, but they are also in sitemap2.xml, but everything is fine. Only one thing worked, namely adding links to sitemap2.xml, Google saw it, but you can’t add all the links to sitemap2.xml because there are a lot of them.

Answer 1

There could be a million reasons.
I remember something similar when only 1 piece of the card accepted SC.
Often problems are due to the Cyrillic domain (SC does not perceive well). It also depends on the cms, the sitemap plugin or the way you created it. In SC sometimes gives information on errors. Not seeing the site or its SC account is guesswork.

Every day there will be this question ( https://qna.habr.com/q/1073850 )?
Doesn't accept because it's a bug that hasn't been fixed for a very long time. Don't waste your time.
Yandex processes these files without errors.
Won, although this may be individual:
- the console does not always show the truth: shows "not received" - inside the file itself "successful";
- does not repeat processing when deleting and reloading: recreate the file, albeit with the same content;
- size: large file (~35000 URL) divided by (max ~2600 URL), although according to the documentation a large file should be uploaded;
- seven downloads per day, although there is no limit in the documentation.
