This is why I ignore performance reports from Apple users. Unless it's something I can replicate on 100% of my test devices, it's not worth the time trying to figure out what weird configuration a some small percentage of a small percentage of users has.
I've actually never heard that criticism. There's like a total of 8 Apple configurations and most of the time, Apple users tend to be on the latest versions of iOS and macOS. I love getting Apple bug reports specifically because they're usually super easy to reproduce. The "weird configurations" type stuff is in my experience some random sloppy Android device sold for $50 and massacred by its OEM.
