I am having the same issue and can't get rid of "Either "offers", "review", or "aggregateRating" should be specified". Why can't we have this as a option on digital products also? It's all my digital products that are returning these errors. I am pretty tech savoy but can not figure out the codes (nor trust myself to be honest) to mess with the codes. Per SquareSpace you place a code or third party in and your web site is null and void. So help us out here SquareSpace!!!!
