I'm not sure if my comment will help you, but maybe it can give you some peace of mind. In May, it was almost impossible for me to work with Evernote. I had to slow down my workflow tremendously, keeping Evernote open on both my desktop and in the browser to check if notes got synced, and also copy-pasting content into Word, just not to lose it. Now, two months later, I am back to my original workflow, and I am trusting Evernote again to keep track of my inputs. So, for me, it got better over the last couple of weeks. I also investigated moving out of Evernote, but my workflow is so ingrained in it that moving out would not only require a huge effort to migrate 10k+ notes but also leave me with multiple tools when I can now do everything with just one.
My apologies for not being very helpful. I hope things will improve soon for you too!
