Thank you, @PinkElephant I used the direct download, not the Appstore version of EN, but I will try your suggestion to use AppCleaner & quitting EN before the Mac sleeps. Thanks!
I've been having this same issue for months now. I have uninstalled & re-installed I'm not sure how many times. I can't believe EN has still not fixed this. iPhone & iPad apps work fine, it's just the Mac app that does not work.
