So I have a site now through Shift4 that I am trying to get migrated over to Shopify. My main source of revenue is a tailored mystery box that I sell customers on a recurring order basis, so subscription functionality is 100% necessary for this change over. I am using Seal Subscriptions as I like the features and love the price.
However, I also absolutely need customers to be able to use text boxes and check boxes for the items they want included in the box. Currently I am using "Variant Option Product Options by Best".
Everything is going great. Except....apparently my Variants app is interfering with the checkout. I have the subscription option available on the product page, I have dynamic payment turned off, but when I complete checkout with a test order, it does not create a subscription. It is only making a regular order.
I have reached out to Seal who says that the options app.
Subscription apps need the selling_plan property, which is included and dynamically generated in your product form.
And what I figured out is that the issue is actually caused by your "Product Options" app, which is taking control over how products are being added to the cart.
