I have several of each. Something eating leaves, the hosta leaves are just gone with ragged edges like bite marks. The potato vines have small holes. Thanks. Have noticed ground squirrel in area of the hostas.
I had the same problem with my hostas. Early one morning I found a cute little bunny taking large bites out of the leaves. My son shot at him with his bb gun and missed. However, I think this has scared the rabbit off and I haven't noticed any new damage.
