On Mac in the "bad old days" of the launch of version 6 (late 2014) and the IMHO bad UI changes that version brought I rolled back not to 5.7.x but to 5.6.x on my "work laptop" (I don't use "local" notebooks so it's not a big issue), though I left 5.7.x on another machine. For me this by now ancient version continued to work PERFECTLY until the day in November I needed to install "Big Sur" and the "ancient" version of Evernote crashed on launch... So I downloaded the then latest Evernote, seeing version "10" and thinking "wow I must have missed hearing about so many versions"... Nope, they skipped a bunch of version numbers and in my opinion "ruined it completely".
I did briefly put the "legacy" version 7.14.1 on my work laptop but it didn't "feel" right so again did a "roll back" to the "real Evernote" 7.14 version taken from its announcement post, ensuring to disable the update mechanism. I feel that are still things that my beloved version 5 did (does) better, but still a better application than what appeared as "the new Evernote"...
Today I read the "we goofed" (state of the product) blog post from December which addresses some concerns but to me only partially addresses the problem. Yes communication was bad but with SO MANY missing features (it didn't even have "settings" when I looked at v10 in November) I personally believe what SHOULD have been done is restore the "real" older version(s) on the download page alongside the new version, not some slightly mangled "Legacy" version buried on a too hard to find (IMHO) support page and actually let people CHOOSE whether they want to live on the cutting edge or use a fully featured version. Just take a look at LibreOffice for an example of this in action!
The irony for me is that the old version 5 Mac icon actually fits better with the visual design of Big Sur than the newer version 7 Mac icon.
