Product.Selling_plan_groups Array (Liquid) Is Sometimes Empty

[Etra]

In our liquid template, we check if `product.selling_plan_groups.size > 0` (confirming a product has a selling plan group attached) and display some HTML if so. We recently started getting reports that the HTML was not being rendered. After further investigation, we found that if the `cache` was cleared then `product.selling_plan_groups` would be empty even if the product has a selling plan group attached. So a first-time visitor to a merchant's store would not see the HTML since `product.selling_plan_groups` has a size of 0. 

We have replicated the issue on Chrome, Firefox, and Safari for the Dawn and Debut themes.

This is a serious issue. I don't know why this hasn't been looked at. Many merchants are starting to reach out to our support about it. For years it has worked just fine. Nothing has changed on our end in terms of using liquid objects to display some selling plan groups. Other apps do this and even some themes as well. Everyone is affected, merchants, customers, app developers. This needs to be fixed...

Thanks for bringing this to our attention. I've created a bug report.

Can you please confirm that when you say, "if the `cache` was cleared," you mean the browser cache was cleared? And if so, at what step in the shopping or checkout does clearing the cache cause the issue?

[Etra]

you mean the browser cache was cleared?

Yes. But to be more specific, it happens when a customer is a first-time visitor to a product page. (Which can be replicated by clearing the cache (mostly, please checkout out the PM with more details)). I have sent you a PM as I do not want to reveal sensitive details. Please check it out.

Thanks for the extra details. The video is very helpful!

This is an extremely serious issue when a merchant is selling preorders. We had a merchant this weekend who missed out on most of their presale sales because of it. 

With preorders, a merchant waits to add a selling plan to their product until right before the sale happens. The caching made the preorder option not appear. To make matters worse, in their product admin they checked the 'Only show this product with these purchase options' box. That prevented customers from even adding that product to the cart, as the cart endpoint rejects calls for products that have that box checked if there is no selling plan in the cart.

This issue really needs to be looked at with the utmost priority!
