In the following version, there is still no way to temporarily decrypt > edit text > reencrypt
10.6.9-mac-mas-public (458440)
Editor: v116.1.14913
Service: v1.26.7
There is a new capability to "Reveal" (i.e. view), as well as "Decrypt." However, the desired functionality is to be able to temporarily Unencrypt the note, update the text, then have the entire note re-encrypt. This is the functionality flow on the Evernote Legacy version, and I suggest should be the goal state for the Evernote 10.x versions.
