Can’t color anything!! – Adult Coloring Book Color Page Review

Why are almost all of the pages locked behind a subscription? It would be great if this app would go back to the way it used to be, When all you when all you had to do to unlock a page was watch a 30 second ad. Another coloring app I have lets you watch a 30 second video to get three coins and when you have 10 coins you can unlock a locked page, if this could be implemented into this app that would be great.
