Here's some context:
A user on a Free account is editing a draft in our text editor. To be able to publish the draft (they get auto-saved), they need to purchase a plan.
When they click on the "Upgrade" button, they are taken to the Checkout flow. After Checkout completion, what is the best way to confirm their purchase?
A screen that says "Purchase was successful" with a CTA that will take them back to the editor?
Or take them back to the text editor, but append a banner up top that says their purchase was successful?
I would think Option 1 would be the best way to go about it. IMO, a purchase is a big deal/big decision, hence a warrants its own single page instead of just a banner?
