App makes purchases disappear

I really love the meditations. The app is frustrating and my purchases disappear frequently. Then it is a real game to get them back. Purchase the cd then download to computer then put on phone. Only way I can see to keep the stuff bought. I was really looking forward to meditating tonight but it is not happening with this app. Spent over $100 on meditations I cant access.
