I can't seem to find the options to sell a physical gift card in my shop. When I go to Settings/Gift Cards in POS, it says there are no gift cards added, and has a link for me to create one in Shopify Admin. I have already created a gift card product and it's available in my online store. I don't see a box to check to allow sale of physical gift cards, and nothing I do seems to link the gift card product in my store to the POS gift card. I have read all the previous files on this topic but all of the solutions involve checking boxes I can't even see.
