How do I edit my product settings?
Once you've created a product (a.k.a. plan) and it has subscribers then you will find you cannot edit the price, delivery interval, billing interval or the product options (a.k.a. questions).
The reason for this is to avoid confusion for any existing subscribers / customers. Also there is a technical limitation with Stripe that enforces the same rules for the same reasons.
The product options / survey questions aren't editable for the same reason. It's to avoid having confusion for you when processing orders. If you have different options / question answers in your orders area for the same product then it would get confusing and become challenging with more and more subscribers to fulfil those orders.
There is a simple clean work around for this. You can "hide" a product from your store by simply throwing the following switching.
Once you have done this, new customers will not be able to sign up to this old plan, now you can create an near identical product and make the changes you want and put it live to "replace" the old version.
