qna_products_apply

# qna_products_apply

Changes app-unlock products in the Q&A app (pApp A00009). Another app code is refused before any request. After a creation the selling price and access period cannot be changed (the original edit screen has no such fields). Called without confirmToken it previews and returns a confirmToken; repeating the same input with it executes once. Ask the user again before executing; this cannot be undone. When the preview has requiresReconfirmation, execute only with irreversibleConfirmed: true after the person confirms again.
