Hey there,

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!

Hey @Marketing_Dept,

Thanks for reaching out! We haven’t made any significant changes to that step, but I’d be happy to investigate.

Are you able to share a screenshot of the data from the Parabola report and how it appears in the Facebook ads manager? Feel free to email us at [help@parabola.io](mailto:help@parabola.io) if that’s easier.
