Prep work is essential to a good finish. If you don't do the prep,
then you will certainly not get a nice smooth finish on top of your
surface. The primers and paint magnify the imperfections, unless you
pour finish on your project.
You can sand out the rough spots if they are raised wood fibers and
recoat. But if the surface was improperly cleaned to be free of dirt,
dust, sanding dust, etc., and it is trapped in the primer and paint I
would sand all of it off and start over.
Wait a few days before sanding to allow the paint to cure a bit and to
keep from simply rolling up the latex and making your surface even
rougher. The fresh latex will easily scratch with sandpaper, leaving
behind grooves that will show in your subsequent coats of paint.
If you sand off the primer and paint, be careful with your prep; sand
your primer as needed and make sure it is glass smooth and clean
before applying finish.

Absolutely, that is part of what the primer is for, sand the primer
smooth then paint.
Sanding a latex final coat may not be satisfactory.

Too late to do what I do. On all wood projects that will be painted I use
sanding sealer first then sand to very smooth. Then primer and paint. Makes
a very smooth finish. WW
Thanks, folks. I ran my ROS with 220 lightly and got to the early part
of satisfactory. It's not baby's butt smooth, but close enough to pass
my wife's inspection.
