I'm sorry as I think this is a common error, but all the solutions I found involve altering your theme's code... there must be an easier solution!
I get an error on one of my products on Google Search Console. Given I only have two products in total this seems very odd and also like it's going to pop up on the other one too!
How can I fix this?
Missing field "priceValidUntil"
No global identifier provided (e.g., gtin, mpn, isbn)
Missing field "review"
Missing field "aggregateRating"
Thanks in advance, newbie here.
