Signing Microsoft from PS4 taking too long

Try an remove your profile from the console , shut everything down and re add the profile when it all comes back up.... that will usually clear things up...

Interesting did you try restarting the console?

Have you checked your internet and connection?

I haven't found a way around it myself yet, I do know the game downloads faster if you turn the system off. Other than that some games will let you play after it makes it to a certain portion of the download but if you start the game while its doing that
itll slow the download speeds again and you may run in to some issues while playing the game.

Please try the first link I provided in my above response, it has contact numbers for support instead.
