Thanks for posting this. The issue is resolved now.
I just updated my Mac Evernote app to version 10.2.4 and now it won't load my notes. I can login on the iOS and web just fine, but not the Mac app. I've restarted my machine but it makes no difference. It just displays the error message: "Sorry, we’re having some trouble. Try reloading the page." Clicking Reload Page just loads the same error message over and over.
