I have enabled online media submissions in some of my assignments. One of my students has an Android phone with the Canvas mobile app installed, and it appears that the only choices for media submissions are Choose Media and Take Video. I only need audio submissions, not video. Is it not possible to record and submit only audio submissions in the Android version of the Canvas mobile app? For what it's worth, my student is currently unable to submit previously-recorded audio files (in .m4a format) because some sort of corruption issue has cropped up that prevents these files from playing in iTunes, my chosen default audio program (this issue is currently being researched by Canvas tech support). Thanks.
