I accidentally deleted one of my apps. I tried reinstalling by going into the apple watch app then opening the app section and clicking the 'show app on apple watch' button. Is says installing below the button. I waited for hours but it wont be installed. I tried hard resetting both my apple watch and my iphone. Then i tried unpairing. And all my apps were gone and none of them would install. (watchos 2, iOS 9 beta)
