PlayStation 4 users have reported issues while attempting to log into PlayStation Network - despite Sony disabling select PSN features to help the service keep up under "unprecedented" load.
In an update on Twitter, Sony said that it was "aware some users are experiencing issues logging into PSN on PS4 due to the heavy traffic we are receiving, we're investigating."
The platform holder followed up the tweet by thanking users for their patience.
Sony announced yesterday that it would be temporarily disabling two of PS4's PlayStation Network features - What's New and the Content Information Screen - to help the service keep up with demand.
It isn't clear how many users are affected or when the service will be up and running as normal.
