I suspect Mosley is probably not on streaming services yet. Deadline reports North American rights were just sold this month, and I can't find anything that indicates it's actually been released anywhere other than New Zealand and Australia yet. (While Wikipedia says "the film is also available on Apple TV," the link is in fact to the Australian iTunes movie store, not to the Apple TV+ streaming service.)
