Yes I did, and if I remember correctly 2.1 seemed a little less lumpy. But just the formula in general, from day one, seemed to be much lumpier than Pulve when I tried it, despite both not containing maltodextrin.
Other products that are smoother include Nano, GlycoGenesis and to some degree Bertrand. At least out of the ones I have tried(oh, and pre-gum Huel, but yeah…). Many others, ofc, have no lumps but are way more powdery.
