I keep getting this error when connecting my store to facebook pixel, has anyone had this problem before?
I found a solution that worked for me. It was suggested to me to delete all browsing history and cookies and then go through the setup again. Since chrome syncs all browsing history and cookies it gets a bit tricky and I don't like to lose my cookies (call me a stickler).
So I used MS edge (which I don't use for anything Shopify or facebook related). Since edge is a clean slate for me I had no issues during the setup. It went right through without a hitch.
Either clear your browsing history including deleting all cookies or use a "blank" browser (Maybe incognito mode works).
