Looking for some help with an issue on Meta - we serve all of our ads using 2 handles (our own and our partners). However have seen (in the wiild on IG feed) that the ads only serve with 1 handle. We turned off all Advantage+ creative features on both ad and account level, also turned off info labels, but issue persists. Anything else that could be causing this? Or is this just some bug?
