I have been using Parabola to pull FB ads data into Google Datastudio for a few months now. Everything had been working perfectly until a week ago. All of a sudden, Parabola was reporting about 30 fewer purchases and a significantly lower ROAS than FB Ads manager was giving me.
My first hunch was that it had to do with recent changes to the attribution window, but I can’t confirm that. Any help would be much appreciated. Thanks!
