I used to have Moto 360 watches with Wear OS and not once did I have issues with the user experience, closing notifications, apps or moving around the screens in general. It was all consistent and simple to use, it just worked naturally. I have a Galaxy Watch4 now and it's a million times worse, when compared, for the most part it's only annoying and harder to use. Totally disapointed but will have to stick with it until maybe, hopefully, one day it makes sense..
