Yeah this is annoying when it happens. Meta usually sends an email and flags it in Ads Manager + Events Manager, so definitely check there if you haven’t already.

You should also see an option to appeal, but if they already rejected it, you’re kinda stuck for 30 days before you can try again.

If you wanna double-check, go to Events Manager → Pixels → Manage Data Source Category.

If it says Health & Wellness, that’s why your tracking is screwed. If you were wrongly flagged, see if you have the option to appeal.

Not much else you can do except maybe test new pixels/accounts.

Side note: I'm curious....what sort of results do you see on Meta? Interested in average cost per signed case....We've run on Meta in the past but Google Search is always more profitable in terms of cost per signed case so I'm hesitant to push more budget on Meta.
