Hi just experienced this issue today. Have never had a problem on my PS4, now the app will not load. Just get a black screen. Have tried reinstalling. Version 2.05, the latest version (so it tells me).
Is there a solution? as I have found nothing that has worked.
Ps4 app is on the latest version. I can connect and play through my playstation but app still showing me the black screen with logo and a message that says "Error. Failed to connect with Playstation Network"(something like that. I ve trued everything and found out that i cant even link my spotify account to ps4. It just wont link. I cancelled my premium because of that because it sounds so simple to fix and yet impossible to even find the issue!
