PlayStation users may be unable to log in to Diablo 4 and see an error: Unable to Find Valid Licence for Diablo IV. (Code 315306)
Do not fret, there is a solution however! This is currently a known issue but you can get around this by purchasing anything (free or paid) from the PlayStation store you will be able to log in.
For example, start the download for one of the free PlayStation Plus Games of the Month and you will be able to get in or buy a small bundle of coins if you were going to do that anyway,
