Might be an Idea to pin this one to the top as this will be useful information.
If you are playing on PS4 & were having issue's logging in. Make sure you are in your countries Play Station website. As the link not logged in on your computer goes to the American site on default.
For if other consoles are doing this too. Then maybe try the same thing.
I hope this is a helpful bit of info & please enjoy uploading.
