As with the previous customer, I too am having issues with the PS4 version of DA:1 GOTY digital copy. I've made sure that my EA and PSN accounts are properly linked. When I look at the game library at each DLC, the PS4 was indicating that they were all installed. The game connects to the EA servers just fine as well as it accesses the Dragon Age Keep if I'm starting a new character. I've closed and restarted the program as well as restarted the PS4.
The only thing that I have not verified is whether or not the game requires an active PSN Plus account to access the DLC's initially. I know that it is required for multiplayer use and for uploading the profile information to Cloud.
Please, any help to resolve this issue would be appreciated.
