Love the app BUT... – Star Scales Lite For Guitar Review

Since 11.3 Apple upgrade all my multiple apps keeps signing out ...Grrr!!! Anyone else got this problem??? I really love this app but Apple 11.3 is a pathetic problem child that’ll bounce me off of it like ...FB, FB messenger ,iBook ,etc etc. Do I get charged for every time I open this app over & over?
