I too am using a Mac and I found the damned popups HUGELY annoying! I run a business and sometimes record Zoom meets, only to have Evernote TELLING me 'There's a New Update'. Well bully for them! I don't give a damn. It REPEATEDLY does this, and after having been on the FREE version I then upgraded as I was saving a lot of material. However, the problem then started, and popups would crop up in the MIDDLE of a Zoom call! That is REALLY out of order! How DARE these people MESS up other people's business meetings by doing this. I approached customer support (again a fair bit of searching to even achieve that!) and after FIRST saying I couldn't stop it, then went on to tell me to reinstall and delete old copies, and it should then be okay).
To Evernote's credit they DID respond quickly. But I did what they suggested (even though I feared it wouldn't solve anything) just to see if it did stop those pesky popups. Well, a day or to later they ask for feedback, which is WAY too early, as there were no updates during this time, so I wanted to wait and see if the update notifications would cease. Well, guess what? The next time I was in the middle of working AGAIN the wretched UPDATE notification pops up. I roll my eyes, seethed, and immediately got back to them saying how that's IT, I'm NOT paying for mere frustration! I told them it's just totally UNACCEPTABLE and to I wanted a pro-rata refund. They did this, and immediately I found I couldn't even save ONE page, as it was over 25mb! There is a 40mb monthly limit, so 25mb is more than HALF a month's limit! WHAT?
What I DON'T understand is that I was using their FREE service for a couple of years without ANY 'bandwidth limits'; but as soon as I return to the FREE version from Premium it's WORSE than before...........The cynic in me says it's because they WANT FREE-account users to upgrade again, if downgrading, as I had NO limits prior to paying for a Premium account! It's a GREAT piece of software, don't get me wrong, but now it feels like I'm being PUNISHED. In response I've abandoned Evernote use altogether now! I don't even log in, so don't get the wretched update notifications either. It's more trouble, but I VALUE NOT being interrupted, so now save documents to Excel spreadsheets - yeah, I'm THAT determined NOT to use Evernote again! A DREADFUL experience, IMO!
