Thanks for weighing in on this topic. Here's a bit of information I can add since I put up the original post. I thought it might help to temporarily upgrade to a paid subscription ... just for a month ... to see if that would help with this issue since a paid plan allows for a Note size of 200 MB. It made no difference. I'm getting the same message. I too thought about exporting the Note, but the error message is so persistent that it doesn't give me any opportunity to even select the Note to try and take some alternate action on it. Again, what is happening is that I click on the Note, wait for it to open, the error message pops up, I click OK, the message goes away for 1 second or less, and then pops up again. I can repeat this process multiple times, but the message continues to pop up, and when it does, Evernote does not allow me to take any further action since the system freezes once the message comes up.
