Troubleshooting SubFlow
The subscribe option is missing on the product page
Add the Subscription Widget block on the published theme, and attach the product to a selling plan. The customer portal lives in the customer account, not on the product page.
A block that shows in the theme editor can still be absent until you save the published theme.
Cancel did not show a reason or a save offer
Customers pick a reason when they cancel from their account. A save offer shows only when you have written one for that reason. Cancelling a subscription yourself from the admin list is a different step, and it does not show that screen.
A product on a subscription is out of stock
You can record a substitute. Open Out of stock, pick the product, and record the substitute. Recording it does not mean the subscription changes on its own.
Upcoming renewal emails are not going out
Set a sender name under Email, and leave upcoming-renewal emails turned on.
The rent-to-own widget is missing
Rent-to-own is optional and stays off until you enable it. Add the Rent-to-own widget on the product page after you turn it on. It is not required for ordinary selling plans.
Still stuck
Email [email protected] with the shop domain, the page URL, and what you expected to happen.
