I would get notes that would not sync correctly, forcing me to resolve it by hand. Even after doing that, it would still have sync conflicts. This was core functionality that just didn't work.
During this time, they were busy jamming in features I definitely didn't want or need. Every release would be a slower, buggier version of its previous incarnation.
It was during this time frame that a lot of people jumped ship. The app was so bloated and buggy by that point that even OneNote seemed like a viable option.
It didn't help that Evernote made it as difficult as possible to get your notes out of their system. It took several download attempts to successfully get my archive out of there. It might have also been due to the large number of people leaving their platform.
The handwriting was on the wall when they started selling knick-knacks on their website. Things like Evernote branded Moleskine notepads and dress socks. It's like they completely abandoned their core competency and went off in some left-field marketing direction.
It's a real shame, too, because Evernote was an amazing app when it first came out.
I'm giving org-mode a spin these days on my desktop. Need to figure out if there's a way to sync/view it on my Android device, but I'm getting kind of tired of dealing with all the different, proprietary SaaS note taking services that go to shit after a few years. At least with Emacs and org-mode, that's one less thing to deal with.
