Where do you mean in the gear app?
When I open the gear app on my phone and I scroll down to the bottom there is not any mention of "more". Just three featured items.
If I open the store and scroll down "more" is not at the bottom of the page as well. If I open watch faces under categories in the store and scroll down they show three featured faces at the bottom but not a "more".
If I search the store for Mr. Time, Time, B XI etc.... nothing comes up at all.
I am using a Sony Xperia Z3. The phone works fine with the watch but maybe there is an issue since I am not on a Galaxy with the gear app not being at the same revision? What type of phone are you using?
