No errors in console, works in Safari on OS X but not on safari on iOS, nor Cordova.
Dom is not completely rendered from what I can see by debugging on safari iOS. The slider content was ingested but the output of the directive is missing.
Tested on iOS 8.3 and 9.0 and 9.0.1. Same on all devices. Tried with the nightly, too. No change. Very strange. I used the example markup from the docs.
Any idea on where to start debugging? Are there any known issues?
