This is becoming a real serious issue! In my case (and this happens on both windows version and web ... not sure about ipad or android yet) 1. I sort my notes (in a particular notebook, or when viewing a tag) - for Title-Ascending 2. this is where I notice that there are notes that are in the WRONG SORT ORDER !! (this was my original problem - but it gets worse!) and sort order is very important, since, when writing a book, I have chapters/sections sorted by the note title eg Chapter 1.0 Chapter 1.1 Chapter 1.2 .. Chapter 4.0 Chapter 4.1 etc --- but I noticed that maybe 6-7 of the 100 notes are out of order ... e.g Chapter 1.0 Chapter 1.1 Chapter 1.2 Chapter 4.1 Chapter 2.0Chapter 2.1.. Chapter 4.0 Chapter 4.2 Chapter 4.3 etc ----- 3. So i tried to retype the note to see if it would go back in order BUT after I retyped the note title for, eg, Chapter 4.1 Evernote made a copy of the note (so there are 2 notes titled Chapter 4.1) 4. AND when I tried to delete the duplicate note they BOTH got trashed! 5. In the trash ... both copies of chapter 4.1 appear I restored one of them, and BOTH got restored! 6. the only way I could (some times) get this to work ... is to create a new note, manually cut and paste the Chapter 4.1 contents, and retype the title into the new note this worked most of the time,but not all the time! sigh .... very tiresome ... and also very instable, for a mature product, that I pay for every month!
