Thank you for using our application!
We have removed the “Caching” function by Apple’s policy and Youtube’s policy about copyright rule. If we try to bring the “Caching” function back, Apple will remove our app from AppStore and we can’t help our customer to resolve issues as update for the app. We are sorry about the inconvenience !
Thank you.maryam commented
