I have not been able to use Evernote on Mac for months. It almost always fails. I managed to clean my computer and reinstall the app yesterday (the newest version). It worked the first time, and now it can't open again unless I attempt multiple times. Sorry, we're having trouble loading Evernote.
I can use it on my iPad and iPhone, but it's frustrating paying a premium price for a program that does not work seamlessly like it used to.
