Used to be able to purchase one book at a time – Lake: Coloring Book for Adults Review

I used this a couple years ago and came back to it recently. First of all, I never deleted the app but all my previously colored free and purchased pages were gone when I logged back in. It used to be that you could purchase one artists book at a time, now that is not possible. I will probably be deleting this now since all my prior work was erased and they locked every page behind an expensive subscription paywall. Huge bummer, I used to use this constantly.
