I am creating a mobile map package (MMPK) and set up my map in Pro to exactly what i want it to look like. I export and the load the mmpk in my application. Everything looks great except my stream line layer will not label like it does in Pro. No labels even show up. I have checked the visibility range, exported the layer to a gdb & shapefile, switched the labeling engine from Arcade-VB-Python and still nothing will make them show up in the mmpk. I have also deleted all fields that are not needed in the line layer.
Any idea whats going on? I have other line layers (Roads) and those label fine.
