Hi Igor,
It's important to mention that Google Search is totally different from DDG, Bing and others. The fact that they do give access to the cached version doesnt mean there is a problem.
I've seen lately that the 'view cached version' option is not shown for all results.
This could possibly be that Google is testing how much it is used.
If that's the case I'd suggest replicating the searches in a logged out session, or maybe another browser.
If you consistently dont get the option, it means that it is fully removed for that search and/or result/page.
Believe me I used to rely on it for may 9-5 job. I had to stop using it because it was quite unreliable.
Hope this helps,
All the best.
Gaston
