I have go my app running well in the browser and it also works well on iPhone 6 and iPad 3 when it has EVENTUALLY loaded.
The app loads initially very quickly, however there is a LONG period of unresponsiveness. During this time the three bar menu (as as the initial Playlist sample app) is not displayed. As soon as this displays then the app functions fine.
The log shows the belo quickly, then I have to wait about 40 secs to 1 min before the app becomes responsive.
The xCode log is below.
