I was able to load my saves again so it's fixed now. I'm guessing the new patch today cleared this glitch out. Just in case you aren't able to load a save, this is how I did it:
1. Remove the Dragon Age disc
2. Delete System Storage data for Dragon Age (don't delete the save data!)
3. Upload your Dragon Age save data to online storage (only if you have PS+...it may be unnecessary but forums said to do this)
4. Delete your save data from the system (make absolute sure that your saves show up on your online storage, if they aren't there then this will cause you to lose your data permanently! Skip this if you don't have PS+).
5. Cut the PS4 internet connection off (Bioware reps said to do this, it's weird I know)
6. Put Dragon Age back in and let it finish installing
7. Cut the PS4 internet connection back on, then download the patch by pressing Options on PS menu screen then select Check for Update
8. Once that is done, then press down on the PS4 Menu screen to highlight Related Items, press right to select Add-Ons. Then on the next screen press X on the arrow icon to the left of the Flames of the Inquisition DLC. Then let it finish downloaded.
Once all of that is done it should then work. I'm sorry there's so many steps. I've had the hardest time the past two days trying to get this going.
