title: My polymer project is not up to date
body: <p>I have been working on a polymer web app which I started in polymer 1.0
  My problem is though i push new code some times the web app is in old version only. To solve the problem i disabled service worker(To avoid caching) and added time stamps to my back end APIs. Still I am facing the same problem.Suggest me solution.Also some times some elements don't respond and render.</p>
