Some games have been patched to resolve the issue; however, that's something the developer needs to do (and QA), so it won't happen on every game. Compare it to what Microsoft does (developers get that functionality by default), and it's frustrating as a user. Along the same lines, Sony also has issued different title IDs for bundles vs. the base game. Horizon: Zero Dawn[0] is one such example; I had the disc version, beat that game, and then wanted to play the expansion when it was made available free-of-charge last year. However, the free version was a different title ID (CUSA10237) than the disc version (CUSA07326), and neither was updated to pull the save file from the other version, so I was stuck restarting the game from scratch instead, losing about 60h worth of progress. This isn't a hardware issue, it's entirely in that Sony hasn't made the proper investments in their backend or system software to make these transitions seamless.
