Annotate multiple PDFs in Canvas Teacher App not working

[rodys]

My students submit PDFs of their assignments and then I grade using an Apple Pencil in the teacher app. Is ice the last update, if a student has submitted multiple files, I can only annotate the first one using the app. If I navigate to the student’s next file, nothing happens when I touch the pencil button to annotate. I can still grade the other files on my laptop.

I figured it out! You can’t annotate while the right side is on Files, but if I change it back to Grade, it works again.
