The app don’t work – Photo Vault Pro ™ Review

I bought this app with my hard earned money, thinking I will enjoy it, only for it, to stop working after a month or so. This is because the app owner is supposed to update the app to IOS 11, without that, this app is an abandoned trash. I need to go to see a lawyer and go the apple office, and see if I can sue this ripped off app.
