Great, but there are some problems

So I’ve payed for a month membership on Recolor, but when I tried to use the colors that were for members it told me that I wasn’t a member. I know my membership hasn’t run out because I purchased it last week. I’ve tried restoring my membership, but it will say something like no active membership. Also, sometimes when I open Recolor it won’t show me any of the pictures that I’ve colored and will only show me some pictures in the library and gallery. I’ve tried deleting and reinstalling the app, but it doesn’t help. I’ve tried using the app with and without WiFi and on different WiFis so I know that’s not the problem. This problem happens at random times, so I have no idea why this could be happening. I really like Recolor, but these problems are very annoying.
