I have the same issue and now I’ve heard the official statement from Apple... It’s not a software issue. It’s the larger lense. The macro focusing distance is larger than on 11 Pro Max, and also than 12 and 12 Pro, because of the larger lense.
I called Apple support last week and the guy took the questions to the Apple engineers. Called med back this week with the answer that the fact that the 12 Pro Max cannot focus as close to a subject as the previous models is due to the larger lense. It’s the lense itself and not a software issue.
I asked him if he could forward the email that the engineers had sent to him, so that I could feature the mail in my YouTube-video, but that wasn’t possible. Apple will be putting this info up on their webpage in some way, and they wanted the facts to come straight from them and not from any other source.
I’m making a follow up video on the issue and will be releasing it tomorrow I hope. Until then this is my initial video, when I first discovered the difference between focus on the 11 Pro Max and 12 Pro Max:

In every other regard, the camera on the 12 Pro Max is better (compared to 11 Pro Max, which is quite frankly the only phone it should be compared to since this is the first year that we’re getting a difference between cameras on Pro and Pro Max). Way better low light performance, faster focus etc. Just not being able to focus as close up, which is quite important for me because of the nature of my channel 🤷♂️
