Can Hubspot conversion events be used to optimize Facebook lead ads?

Hi Tertsi
I have just gone through the process of synching our Facebook ads account and then creating the events. They seem ok, but like you I then wanted to optimise our campaigns/adsets to this event, and it wasn’t an option.
Did you manage to find a workaround / a solution that allowed you to run Facbook ads campaigns effienctly towards Hubspot lead generation forms being completed / lifecycle changes in the end?
If so, I’d love to understand how or who helped you to find a solution?
Thanks
Simon
