Thanks for the update.
I can add a favourite as a widget now, but they still don't show up when choosing "dynamic".

I thought so but then the question is, how did you add your playlist to favorites in the first place? I mean, you have to select your playlist somewhere in KODI to be able to add it to favourites. In this case just open up the context menu and select "Add to custom home" instead of "Add to favourites". Or did I miss something here?
