"Product Collections" and/or "Product Tags" as limitations
Unfortunately, we do not provide any way to define product tags or product groups mandatory in the app.
As for the "Product Tag" in groups, we wish it was possible, but because of certain Shopify API restrictions that information is unavailable to our script at the time when the limits are verified. Hopefully, this changes someday.
What we have is the option to add each of those products individually at our "Product" settings section by using the group limitation function, It can be based on product type or, say, vendor name for instance.
For more details, we provide customer support via email. Please send your questions or feedback to support@minmaxify.com. We look forward to providing assistance.
