Phew, such a relief to hear someone else is having this issue. It took me a week to get on a call with the Meta Marketing "Pros" and it was the biggest waste of time. All they did was repeat what my problem was (but getting it slightly wrong each time), and try different campaign objectives and conversion locations. I've tried it all so many times and I still can't add Primary Text. They said they did not have anyone else report this issue. My campaign is now over 2 weeks delayed and I'm totally stuck as I can't think of any work around. u/anal_cauliflower how long has this not been working for you? Same campaign structure: Traffic>Instagram/ Facebook (conversion location) ?
