Can't find how to annotate image

A few things to check:

  1. Are you running iOS or iPadOS 13.1?

  2. Is the attachment indeed an image or is it perhaps a PDF? The latter won’t work yet, something we hope to allow in a future update.

  3. Does it help if you force quit Agenda and start it again?

  4. If not, does it help if you reboot your iPhone or iPad?
