The only solution i found is third party apps. But that workflow is more tedious, takes up more space etc, which Apple probably made intentionally.
I just spoke to an apple employee who told me he was unaware of this issue, and I linked him 3 threads on the subject, and he told me he would read it in his spare time. I bet.
I also submitted feedback to apple that they need to fix a software update for this, or at least give us the option to turn the messy auto enhance off. I suggest more people to do this, that way we'll maybe see an update in the near future. I'm crossing my fingers but i doubt apple gives a sh1t about us photographers. The biggest group of users seems to be facebook moms who've never touched an exposure slider, i guess.
Once again, Apple employees, if you are reading this. Fix this sh1t. My phone is twice as expensive as my mirrorless aspc camera, and I should therefore be able have some degree of creative control, or at least be able to post process my images instead of a lousy AI.
