Spotify slow on IPhone

[AndrewJ83]

Hello,

everything worked fine till now:

I have an iPhone 5s with IOS 11.1.2.

Spotify is really slow on everything: loading a song, loading album images etc. even if my connection is fast on everything.

when a song is playing (after a while) the time informations are disappearing and reappear only if I click somewhere, and then disappear again after a couple of seconds.

Why those problems ? Very annoying.

I tried deleting playlists and reinstalling the app, but nothing worked 

please help me 

thanks
