At least one of my notes is missing about half its content. In its place, if you go to the classic editor, is the following on each line that is missing content: "Content not supported This block is a placeholder for Tasks, which has been officially released on the newest version of Evernote and is no longer supported on this version. Deleting or moving this block may cause unexpected behavior in newer versions of Evernote." Is there a way to retrieve the content, I really would appreciate having it back.
