My Question or Issue -

Spotify will not connect to any devices in my home . Chromecasts through the B+O app. 

The app runs so slow and becomes un-usable not playing songs , not fast forwarding , if a song eventually plays and you try and skip to next one nothing happens for several minutes. (it runs as if there is hardly any internet connection, which is not the case) 

I cannot scroll through my library because it is so laggy. I cannot search for new music as again it is so slow. I cannot connect to devices.

Is there an older version of Spotify i can install? 

I have already completely deleted the app and re-installed. 

I have changed phones.

I have turned phone on and off again.

I have deleted cache. 

etc etc 

as above any older versions available that work i could download instead
