Hi, I have had an Apple Watch for just a few days and am getting used to the great features. I have reached the stage where I want to download a 3rd party app, but seem totally unable to do so. When I open the Watch app on my iPhone 5S the "home screen" has 4 icons at the bottom, My Watch, Explore, Featured and Search. The My Watch one is lit up, if I touch Featured to try and access the App Store all I get is a completely blank screen with the Featured icon now showing blue. The same happens if I touch Explore or Search. IPhone is running IOS 9.3.2 and the Watch 2.2.1 Any ideas what is the problem and how to fix please?
