If I have a video loaded as a document and the video has an audio track attached to it, will the audio play when the song the video is attached to is selected. If there is also a recording attached to the song, will the audio track of the video play?
Yes and yes.
BTW, the on-screen video controls are broken in the current iOS app version, but that will be fixed in the next update in about a week.
Thank you for the advice. Glad to hear the video controls will be fixed. That was the subject of a technical issue I raised with you a few months back.
