I think this is intended but not functioning or I am coming up against the grey areas. I only have Switch. I am starting to see that some titles say they have dlc included with them or available for them that are not, that is they are on Steam, but they do not operate as purchasable or seperate dlc or editions on Switch. I am also knowing, even though I have limited myself to Switch, I am seeing recommended titles that are not on the platform. I also seem to be seeing a number of Japanese games as if they are US releases with US release dates, a recent Japanese Cotton title is one of these, rightly confused me. I think some content inclusion is also getting mixed up too. I bought a special edition of a title that was supposed to have four comics included with it, but that was not on the Switch version.
Aside from this, I would appreciate an ability to attach tags to titles and to mark different folders as owned, wishlist, etc. also, maybe, when viewing the dropdown dlc or recommendations we might could see our owned or wishlist status there?
