Dear Gazumped, these attachments are straightforwardly editable with the Windows app. The web interface downloads the attachment when I click on it. I can then edit the attachment and drag it back to the note. Previously, when I opened an attachment with the Android app, it would ask me whether I wanted to view or edit. This no longer happens. Also, when I finished editing the attachment, the app would ask me whether I wanted to replace or append the file. This also no longer happens. As you say, I could save the attachment, edit it and re-attach it but that would be a little cumbersome
