Apple's support forums aren't a place where Apple provides their users with support, they're where Apple users seek support from other Apple users, mostly unhelpful and often inaccurate support.
In fact, 99% of the time the only advice you'll get is "restore your iPhone", "restore your MacBook Pro", "restore your Apple TV" and so on into bitter infinity.
Yeah, I miss the days back at the start of the decade when I would brim with delight over an email notification that a senior engineer / moderator had chimed-in on my thread on the Apple dev forums.
Checking the dev forums was my favourite thing to do in IT class at school :)
These days, I get that (especially now that they're open) the forums are too saturated with content to have engineers on the ball all the time... But the Captain Hindsight in me thinks they could have done with some keyword notifications to nip instances like this in the bud...
I ran into a bug with High Sierra, posted in the user forums and was contacted by a friendly Apple Engineer a day later. So they do read them, but apparently not close enough.
I could see how someone would dismiss a posting like that with an "this cannot possibly be true" shrug.
