2.0_300 - Add a "3.5"
Change (3>) text to just say "The final part of this step is for me to confirm or provide my credit card information."
On the new (3.5>) have text say "With digital check-in complete, I move on to select whether I want a digital key. At some hotels a digital key isn't available. But when a digital key is available, that's what I select."
3.5 will have a new screen cap. If moving some of these clickables to another screen is necessary, then that is ok.
