Ongoing performance issues on iOS devices

[shannonsimpson93]

so ive posted on here before. and i have updated and everything but the app still isnt working on my galaxy s9. i would like to know if its the phone or the app itself.  cus it was working 2 updates ago. now its not. 

it takes a long time to load into the app. then when i try to open any Playlist itjust spins with a black screen. and if im lucky and it actually works after about an hour it says that its using 14%of my phones cpu. 

please help.
