My app disappeared and erased all content – My Secret Folder™ Review

My app disappeared from my phone and all the content from my folder was erased. The app logo looked different though, but i went through all my purchased apps and found out this is the “new secret folder”. I had a lot of memories that were vanished and I am very upset that this happened. If anyone knows how to fix it please help.
