In case it’s not clear from this post https://daringfireball.net/2023/03/tweetbot_and_twitterrific_face_the_cliff the reason you’re being asked to tap a button that says you don’t want a refund on the remainder of your Twitterrific or Tweetbot subscription is that Apple WILL send you a refund if you don’t do this. You must explicitly opt out of receiving a refund.
