Hi there,
I've not had any problems with my PS4 at all until yesterday. Suddenly the dashboard menu has started working incredibly slowly. If I try to scroll left or right faster than once every few seconds or so, the whole thing freezes for up to 10-15 seconds before progressing. Notifications etc also do this sometimes when first opening them. The strange thing is that games work perfectly once I'm able to launch them with no lag or anything so I'm not sure what's up.
I have tried rebuilding the database with no success and if I am not connected to the internet the problem isn't there. Is anyone else having this issue as of yesterday? Could it be a PSN issue as it tries to get the social aspects of apps as I scroll over them?
