 ## Limitations
 - Wrapping `Context` with Phrase can lead to issues with `WebView`. `WebView` interactions which access Android resources might fail and can lead to app crashes. E.g. the opening of an HTML drop-down menu. Consider to use `Context.getPhrase*()`/`Resources.getPhrase*()` extension functions to get translations via Phrase. These functions do not need a wrapped `Context` and the wrapping can be removed or disabled.
