Hi Antonino,
Sorry for the delay, I have been away.
I have tried the above code and it appeared to work fine.
I am getting advanced pixel tracking when I test the pixel and I seem to be getting more information than I was before.
I am back to getting add cart, view content, check out, etc with the product ID and various other information including what the user is logged in as and their details.
Sincerely,
Andy
