Mac Desktop app not Scrobbling

[user-removed]

Plan-(Premium)

Country-(UK)

Device (Mac Pro late 2013)

Operating System (MacOS 10.12.6)

My Issue

 When I use Spotify on my Desktop app it is not scrobbling.

I have logged out and back in - Still not working
I have deactivated and reactivated Scrobbling in the Applications settings - Still not working
I have tried it on my iPad - It does work

I have tried it on my iPad via Soptify and Sonos - It does work
I have tried it on another computer, namely my iMac also running MacOS 10.12.6 - It also does not work.

Any suggestions how I can get it working? 

Or am I gonna have switch to Apple Music??

Got it working by disconnecting Last.fm via Last.fm's  "Settings - Applications"  logged out of Last.fm and logged back in then reconnected to Spotify.

Hopefully this will work for my home computer
