I've got some faculty who are finding a lot of use for the Moodle app, so first, thanks for that! But they're finding it limiting that they can't annotate PDFs within the app, and I'm finding it limiting that I can't recommend that they download files to another app, mark them up there, and return them.
So, just as a sanity check (since it isn't addressed in the FAQ) - am I right that the Annotate PDF feature isn't available in the app, and neither is the ability to upload feedback files as part of grading?
