This is an old issue from Season of the Splicer which has persisted for months, and I haven't seen any mention in the Known Issues list in quite a while. I use a DualShock 4 on Steam for PC Destiny and sometime during Splicer, a hotfix came out that cause a bug where Destiny now thinks my PS4 controller is an XBox controller, so the inputs all display in the UI as XBox inputs, and the touchpad and share buttons no longer function as they should since all DS4 buttons have been auto-interpreted to XBox inputs. As a multi-platform PS5 and PC player, it's really annoying to have this inconsistency in controller input on essentially the same controllers. All other Steam titles properly recognize my DS4, and other clanmates and friends have reported the same problem.
