After many rejections, I finally figured out a way to get verified without having to write more code to opt-in/opt-out. See attached pictures. My Campaign Use Case is Low Volume Mixed but I don't know how much effect that has on it. The scrubbed link is a Dropbox link to the consent form attached here. Make sure that you copy a link from Dropbox or wherever that says "anyone with the link can access" or similar. I had a couple people test the link just to make sure I wouldn't get rejected just for that. I imagine that the [insert company phone number] could be an email address instead, but I didn't think of that until afterwards. I hope this helps!
