I didn't provide any details, as it was more of a general whinge about Evernote, on the back of a history of frustrations with what was once a fantastic app and is now a bloated mess which still doesn't get basic stuff right. My frustration is leaking through.
A lot of people have had problems with their updates, I really don't think it's anything on my end.. I don't have this issue with other software updates and there's nothing unusal about my set up (eg a security suite) that should stop what should be a simple process. I've done various uninstall/full reinstalls along the way. Sometimes it works, sometimes it doesn't.
But just FYI, Windows 10 Pro, using the app (the web interface works fine). System is up-to-date, no unusual software suites etc.
