Can't link / login on Playstation 4

[CounterDavid]

I have a PS4 and when i try to login on the app it asks me to link accounts with PSN, and after i click on link it says my account is already linked then brings me back to login page. On the playstation accounts page says that my account is not linked to any spotify account (https://link.playstationmusic.com/spotify/details/ ).
 
I've try contacting Sony with this problem, they checked out and said that is a problem on Spotify side, that theres really nothing linked to my account, so im here.

i've attached a picture with the playstation site saying that theres no account linked and here's a video showing the problem on my PS4:
