Wow, add me to the list of users whose posts Apple is deleting on these boards. As much as I want to give them the benefit of the doubt, that kind of behavior leads me to believe that they are hiding/not acknowledging a problem. I'll do my best to recreate the post here, but I'm sure I'll be missing some critical info:
Spoke with someone from Engineering who assisted me in sending log files for the No Service issue on my 6S. I was very clear that I live in an area with spotty service, but would be travelling to an area with 100% coverage soon. I captured additional logs in the "good coverage" area, but when I offered to send them, I got a polite "thanks but no thanks".
Also had an appt at the "Genius Bar" where they looked over my phone, pronounced it is excellent condition and were willing to give me $150 credit towards a new phone. Unfortunately, a new 6S is $300, and new 8 is $799. My phone was paid off. I can't afford to drop a couple a bills on a new phone, and it's really annoying that Apple seems to think I should, even though the phone was working great before ios 11.x, and is not now.
The entire reason I am with Apple is because by being responsible for the hardware and software, the devices are supposed to be more stable. If that is not the case--and they are shadily deleting posts with complaints--then there really is no reason to be loyal. What a shame.
P.S. I'm saving this to notepad so I can easily re-post it if (when) it is deleted again.
