I've just been chasing this with help.ea.com. I have a current EA Play subscription via my Gamepass subscription. Things I've noticed:
- At Origin , when I'm logged in it shows me as owning all of the DLC, including Trespasser.
- At Dragon Age™: Inquisition - Trespasser for PC | Origin, it clearly states the Trespasser DLC is included with EA Play, and when logged in I get the green tick and 'You have this content'.
- In the EA Desktop app, it lists me as owning 7 out of the 8 DLC. I get given a price for Trespasser.
- The game itself is listed as 'Included with your EA Play membership, and I can download and play it just fine, with all DLC apart from Trespasser.
- If I go to any of the working DLC screens in the EA Desktop app, I get an info box at the top with the cover art and a green tick 'You own this add-on'.
- If I go to the Trespasser DLC screen in the EA Desktop app, I get the info box at the top with the cover art and nothing else except a pulsing 'loading' icon. It looks like the Desktop app is failing to query the ea.com servers for ownership information about this DLC, and the EA Desktop app is unable to complete rendering the screen.
So far I've just gone through the usual tech support drill. We have manually cleared various Origin caches and reinstalled EA Desktop, and we have used the App Recovery option and reinstalled EA Desktop, and rebooted, and completely reinstalled Dragon Age: Inquisition. Situation has remained unchanged. Some sort of escalation has been done, but I can't see any status of that, so I guess I just need to keep annoying help.ea.com if it doesn't get fixed 'in a few days'.
