Hi, thanks for your reply.
I took your suggestion and added the wix app store, however, the product database in this is read-only as well and I am unable to add extra fields to the database. The current product information fields are not appropriate for the product I am selling.
There must be a way of adding custom fields to the product database or at least have a way to change the database the wix store uses sop it can pull all the extra fields needed.
I am having to source other platforms at this stage.
