@jkl you said "the triple camera setup on iPhone 13 Pro doesn't have the same problem, which tells me that it's fixable!!"
Does the 13 Pro switch between cameras automatically for close shots? I only have a 14 Pro here, it did automatically switch before updating to 16.0.2. Now I'm curious what the 13 Pro behavior is, whether it does the automatic camera selection.
Again, it used to be the case for the 14 Pro, but not with 16.0.2
