Apple has added another step to prevent users from accidentally signing up for an iOS app’s subscription – or, from being tricked into it by a scammy app not playing by the rules. The company recently rolled out a subscription confirmation dialog box that pops up as one final step to ensure you meant to opt in to the subscription being offered.

The change to iOS was first spotted by app developer David Barnard on Twitter and reported by Apple news site 9to5Mac.
