Ps5 not downloading updates

[Padds1138]

So there's a new update for ac valhalla but my ps5 isn't auto downloading it. I've had this problem with a couple of the patches for this game. The last 2 times I had to uninstall the game and re installing it seemed to get the update downloading. But it hasn't this time. I get the system updates no problem when they are released it's just game ones. Any idea what the issue maybe. Thanks
