I have accidentally added 2 facebook pixels to my website and wanted to remove one of them. I looked up the information for deleting the facebook pixel, but the documentation says to go into theme.liquid and search the code in the <head></head> tag, but there is no facebook pixel code there. I have added the code through Facebook, not manually and I am using the venture theme.
Mego, how did you manage to fix it with Google Tag manager? I've just deleted the Facebook Messenger from the 'tags' section yet messenger is still appearing on the home page? It's driving me nuts!!
