Options+ is complete and utter garbage compared to Options. Unnecessary upgrade that the Options app suggested I do. Initially I couldn't seem to add any device, then suddenly my MX Master 3 was added thrice. I tried deleting all of them so that I can add it just once, but it didn't delete them from the app and now I can't seem to add my mouse at all. It's beyond me how a company as large as Logitech ships such half-baked software that completely destroys the experience of using its own products. I will be deleting Options+ so that I can go back to how I'd configured my MX Master 3.
