Unusable slow on mini 2 with iOS 11

Scrolling is so laggy and when it comes to switching between Albums, the title covers needs to be reloaded every time when you go to a new (already downloaded) album and it takes a lot of patience to wait until what you have clicked finally begins to play. Sometimes you even hit something else by accident, because the scrolling has not finished in time.
Furthermore the music gets interrupted every now and then.
(iPad mini 2, iOS 11.2.5, fresh factory reset)
