I have watched warm (160F) gelatin solution, poured gently on top of cold beer in a carboy, form a visible layer and, as the temperatures equalize, drop to the bottom taking the haze along with it. No mixing involved.This is correct. Also, gel solution is NOT a positive or negative-charged thing like Whirfloc is. If you have seen pictures of some of the clear beer I have posted, that is a result of simply opening a keg and pouring some gel solution on top and sealing the keg back up. At that point the beer is cold and flat and I would start carbing afterwards. The solution is warm, the beer is cold so the gel sits on top at first and slowly falls dragging everything else down with it. It's a physical reaction, I believe not a chemical one. My comment on the pH is that I focus carefully on my mash pH but could slight variations in my pH adjustment cause some cloudiness? I'm not sure. On this blonde ale I have that is cloudy, I have absolutely no idea why it's cloudy. It may have been gelled TWICE and everything else regarding the brewday went as planned. It just happens sometimes but the vast majority come out very clear. Are you sure you reached terminal gravity? Maybe the yeast didn’t finish and at fridge temps it is still working albeit very slowly. I have had this occasional problem also. I am not sure what the issue is. The above is a wild guess.

I never mix gelatin and it works great in my opinion.
