Where can I get help signing in? Error message.

[NWOStunna_PSN]

I cannot log onto the companion app. I can sign in to get access to message board, but I cannot log onto marketplace. I get an error message. Where can I get support? My account is not suspended and I don’t understand why other are logging on but I can’t.

Maybe due to the update just released?
