Looting enchantment not working on leather, feathers, maybe more

Playing newly released MCPE 1.2 iOS. Looting [III] enchantment [on diamond sword] not affecting amount of leather dropped [from cows] nor amount of feathers dropped from chickens. Does seem to still affect amount of meat dropped.

I suspect maybe other loot is broken too, but it was quickly obvious slaying cows, both ones I’d fed/bred as well as new spawns. Previously, I’d easily average 2+ leather per cow after a spree using this sword. Now, after killing a dozen cows, I think I got 2 or 3 leather total.
