Hey, @rosanam .
Rio here from the Shopify Community team. I understand that you have created a meta pixel and it is active, but the meta pixel helper extension shows no pixel on your page. I’m happy to look into this issue for you.
In order to assist you better, could you please provide me with the domain so that I can take a closer look? Once I have this information, I will be able to investigate the issue further and provide you with a solution.
