Here’s the response I got from the support team in case anyone has this issue in the future:
Since you've connected your Instagram page to Manychat using the new registration flow (introduced after June 14, 2024), which doesn’t require linking to a Facebook page, you have experienced issues with the Instagram Ads trigger due to Meta's lack of support for this feature.
I understand this can be frustrating, and we’re committed to offering the best assistance and alternatives. Here’s a workaround you can use for Instagram Ads:
- Consider utilizing the FAQ option in your Instagram Ad’s message template and replicate the keywords from your FAQ options in your flows. We have a helpful educational video from one of our Product & Education Experts that explains this workaround in detail. Please see the video linked below: https://youtube.com/watch?si=hM1UFx0frUAcDjmo&%3Bt=712&v=AqFQbTSvYwY&feature=youtu.be
- Alternatively, you can reconnect your Instagram page to your Facebook Page via Meta Business Suite. This will switch your registration flow back to the old one, enabling the Instagram Ads trigger. Please note, however, that removing your Instagram account first will permanently delete your contacts. If this option works better for you, a Loom Recording is linked below to guide you through the necessary steps:
