I've done everything you have asked and this is still the result. In the code, i can debug and see that one MobileBaseMapLayer is added to the basemap and four feature layers are added to the operational layers.
But none of that helps because I see absolutely nothing on screen. Not even a grid. No basemap, no feature layers. Nothing.
This is with your very own Yellowstone.mmpk example.
Here is the code.
