For this yearly subscription, I was able to display the subscription interval below the product name in the Cart. Snippet also displays it in the Checkout page and Thank you / View Order customer pages.
Interestingly enough, when you add a subscription product to the cart, there is no renewal date information unless you scroll to the very bottom and are able to read the very small text below the “recurring total” (see screenshot).
It would be way more helpful if dates (and specifically the WooCommerce subscription start date and end date) showed right under the product name inside the Cart table and in the Checkout page order review, so that the customer knows exactly what they are purchasing before having to figure that out.
So, here’s how it’s done. Enjoy!
