Do a database rebuild. This happened to me at some point, but the quick rebuild fixed it.

How do you do that? Maybe it will fix my (apparently uncommon) issues.

Turn off the PS4 (make sure it is fully off) then hold the power button until you hear two beeps. Then hit rebuild database. It made my PS4 alot quicker.
