I recently updated to version 7.17.1 on my iPad and today I discovered that the "Simplify formatting" option has disappeared. Why is that?! It's an essential feature for cleaning up notes full of crazy formatting.
Thinking the option might be hidden somewhere, I was trying to locate it in a note and ended up converting the whole thing to plain text. I tried for nearly an hour to reformat the note but couldn't get the job done because every time I tapped on the screen to situate the cursor, it jumped to the bottom of the note. I tried closing and relaunching the app, rebooting the iPad... Nothing worked. Only that note was affected.
I had to go to the computer (where I am now because I couldn't find a way in the iPad version to send this message without jumping through the same hoops a dozen times). I fixed up the note, which has now synced back to the iPad and is working correctly. Except that I tried to edit it and the app crashed, for the third or fourth time while I was trying to sort out this issue.
This iOS version of Evernote seems to be rather buggy and crash-prone, besides missing an essential feature.
