Not able to add a Facebook Pixel in ads setup.
I'm trying to integrate Hubspot with our Facebook account. I went to Marketing->Leads Capture -> ads and chose Facebook. The site recognizes my profile and page but when I reach the final step - Facebook Pixel the drop down is empty and I can't enter the pixel id (although I have an active pixel for our website). I have admin rights for our facebook page and FBM... What could be the problem?
