Can't switch to App 
Dear team

I've updated the plugin today and now I'm not able to switch to some appButtons for exemple my config below : 

> "appButtons": [
>                         {
>                             "appId": "com.webos.app.livetv",
>                             "name": "Live"
>                         },
>                         {
>                             "appId": "com.webos.app.hdmi3",
>                             "name": "PS4"
>                         }
>                     ],


Hereunder the logs retrieved with the debugMode :

I'm on WebOS 4.0. The other options like volume or channel switch works fine. 
Working fine before the update. 

Thanks in advance for your help.
