Hi!
I am having troubles configuring the Facebook/Instagram shop as I can not add products to the catalogue through Facebook Pixels. I get a red flag with the error message that the microdata for the pixel are wrong. Does anybody know how to proceed in this matter? I use the prestige theme and have not added codes. I tried to google this, but I am not a skilled coder. Anyone who could help a girl out? 
Hi! Did you tried to use the application for sell-through facebook https://apps.shopify.com/facebook ?
Thank you for the reply!
Yes, I have tried to use the application, but it also states that my products are offline

Thank you for the links! I have tried to understand it, but it seems like the catalogue is not synchronized due to the lack of micro data tags. I do not understand how to proceed.
