Just an update: Evernote Support contacted me regarding their attempt to recover images that I have lost and I recently found a newly created Note containing some of the missing images. So I do believe that the team is doing whatever they possibly can to help recover IF you have reported the issue. However the missing texts are still yet to be recovered, and new images and texts are still missing right after entry, just like many who have expressed so. This is for both Notes with Tasks and without Tasks.
I have given up on the desktop version - the same happened with 10.58, if not worse. Many times I saw another “me” appearing on the same Note when I’m the only user using that Note, and it’s not a shared Note. OR the circle will keep spinning & loading & Evernote would just hang up on me. Having said that, I do observe an improvement recently with the web version. So far, the content are still there (fingers crossed still!), compared to the web version 2 months ago where data would still be lost right after entry. Not sure why there would be a difference - maybe some of the experts here might know? So for those who are facing an issue with the desktop version, you might want to give the web version a shot & see if it works better for you?
