Since I changed email provider, I changed every account I had to use my new email. So far so good, no problem.
But now, I turned on my PS4, and it say I m not signed in. Not a big deal, just need to input the right email.
But going to Sign In just put me on a loading screen. Going to Options>PSN/Account Management only show Sign In, all other options are greyed out.
How can I change the email now? The only option I see is changing it back to the original one from the browser, and changing it back from the PS4, if that is even possible.
TL:DR: PS4 have saved a old email, and try to sign in with it. How to change that email?
