Where’s the first version? – Color Alive 2.0 Review

Why remove the first version? I bought a bunch of these books on clearance for my patients to use only to be disappointed that the first version of the app is no longer in the app store and the books I got require the first version. I don’t get why not have one app for all the books they have.
