Hello,

One of the merchants installed my preorder app, but it is not working as expected because the Product Liquid object does not return selling plan groups. I can see in the admin that everything is set up correctly as usual. Why is this happening?

I tried publishing the theme on another store, and everything worked fine, so the issue must be with the store settings. Who could block the product Liquid object from having selling plan groups?

This did not help; I’m not the only one facing this issue:

Clearing your browser cache or using an incognito window.
