I think they have the functionality integrated into the OneDrive and Office apps. Not sure if they intend to remove those features but it might be a play at upselling the users.
Yeah, this was one of the "simple apps" I had in my utilities folder. Having it bolted onto an office suite sort of kills the appeal. Wondering if there any fixed-function alternatives. Reddit had a few, including an open source alternative, but comments were also saying that they weren't of the same quality. Apparently Adobe has a good one, but it's tied to a subscription.
