Google broke the sitemap submission and how to get out?

Question

Search Engine Optimization

With the advent of the new console, problems with submitting the sitemap began. And completely random.
1. It is impossible to submit an index normally - it reads 2-5 sitemaps from it, despite the fact that there are hundreds of them.
2. Completely randomly accepts or does not accept the sitemap - submit, write an error, change the name of the file - accepts
3. On some sites it does not accept at all, even if you crack - so I bought a domain and I can not submit ANY sitemap.
What to do? How do you get out? Are there hacks?
I read Google forums - dozens of topics about it, hundreds of complaints. Google is 100% aware of this. Is this a feature? Is it on purpose that they fuck the brain?
APD: Tried to ping by url - 0 effect, generally some kind of useless crap.
