iPhone 12 Pro Max Bluetooth keeps disconnecting

I've been having an ongoing issue with the iPhone 12 Pro Max Bluetooth where it keeps disconnecting from bluetooth, regardless of what device it is connected to.

I've taken my phone to the Apple store several times and they've done partial restores, full restores, "board" replacements, and they even replaced my iPhone with the same model, but the problem still exists, it's not due to any software I install as I always wait to see if the issue comes back after every service before I load anything to it.

If you google this problem you'll see that there are plenty of people with the same issue, but Apple continues to play dumb and pretend that there isn't a problem.

So far they have refused to update me to a newer model to see if the issue gets fixed or not, but I will not spend another grand on a phone from Apple that is not in full working order.

Has anyone had any luck with getting Apple to admit that this is an ongoing issue?
