Why do I see a 'No content available' error after switching PlayStation accounts?

PlayStation games and their store content, such as DLCs, are region-locked. They are tied to the region of the PlayStation account used for the original purchase. This error appears when you try to access the in-game store with an account from a different region.

To resolve this, you must use the account from the same region as the game to access its store:

1. Close the game.
2. Log in to the PlayStation account you originally used to download the game.
3. Relaunch the game to access the in-game store.
