Slow WLAN because of Spotify App

[Manuel92]

Hi together,

I have a Huawei P20 lite lite with spotify installed. As soon as i start the spotify app, my wlan connection gets really slow. Websites take forever to load. As soon as i switch to mobile data everything is back to normal.

When i use my Samsung tablet in the same WLAN i don't have any problems - so i guess there is a problem with the spotify app. On the huawei device i have offline playlists for my car, does it might have something to do with that? But the songs are already downloaded, it shouldn't influence the WLAN connection. Also in offline mode the WLAN gets very slow, as soon as i stop spotify everything works fine. 

Does anyone have similar problems?
