1) When it got to the point that I had to link the Facebook Page and Pixel, it gave me an error saying the Pixel was already installed on the page. So I had to go into Tag Manager and remove the Pixel and events codes from the website, although this meant that now all my custom audiences are not available to use any longer. The Pixel codes are the same (the Facebook one and the one Magento pulled in) as the Pixel helper can see track them both. However, somehow Facebook does not recognise this, does anyone know why and what to do?
2) Also, the products' IDs don't match between the website and the Facebook catalogue, even though Facebook is pulling information from the right Magento feed. Has anyone come across this issue before?
Does anyone know how to rectify these problems please?
