Is there a React Stripe or UI Stripe out-of-the-box solution for upgrading/downgrading subscriptions with multiple products? The Stripe portal can only handle upgrading and downgrading subscriptions with 1 product. I don't see anything in the React Stripe or other stripe docs any other ways to go about this other than building a custom UI solution.
Tried to use the Stripe portal or Stripe checkout, but neither of them can handle upgrading subscriptions with multiple products.
You're right, they document the limitation here. If there are multiple products, your end customers can only cancel them in the Customer Portal and they can’t update them. Aside from the Customer Portal, there is not an out-of-the-box UI like you shared and you would need to create a custom UI on your end to update the Subscriptions.
