In Minecraft on the IPhone, simply when you activate the new graphics, the shadow simply doesn't appear in the first person, only in the third person and this gives me a lot of agony because on Android there is perfect shadow and on iOS there is no shadow

this bug and when you activate the new preview graphics on iOS there is simply no shadow in the first person, only in the third person the shadow appears, then there was a time when the shadow appeared in the first person was when I entered a map and a block out of nowhere the shadow appeared, I don't know why on this map that appears in general there is no shadow
