I do these shops often. In addition to using my phone to record the shop, I usually have other recorders running at the same time and am glad I do. Human error, accident, and equipment failure can happen. If I did not have a useable recording, I would not be paid.
Please note that the audio must be in mp3 format. That is really not much of a problem, because there are free, online converters that change audio files in other formats to mp3 format.
You upload your video using SASSIE.
The rotation is 10 days. Look for bonused shop later in the month.
Good luck.
