Thank you very much for your post.
As you may have noticed, I have also experienced this issue, and first reported it to Apple Support on 17 December 2021.
Are you also noticing a related issue of audio content, music, podcasts, or audiobooks, randomly pausing multiple times, as many as 5 to 8 times each hour, during activities, and while listening with AirPods Pro or AirPods Max?
This second issue has been reported here in another posting. Please refer to https://discussions.apple.com/thread/252866714?answerId=256784389022 .
Like many others, I have been very concerned and annoyed by both of these matters in what I had through was such a quality brand, that sells at a premium price, and has a tradition of striving for extreme perfection in all of its products.
I have an Apple Watch 6, an iPhone 12 Pro Max, AirPods Pro, and recently purchased AirPods Max. I updated to IOS 15 and the latest firmware, and was enjoying all these Apple products until Apple updated IOS from 15.1 to 15.2, then 15.2.1, and currently 15.3.
I believe these problems began with 15.2, but I'm certain that I first noticed the stoppage of Apple Exercise App Siri audio progress announcements on my AirPods for speed, distance, ring closures, and activity completion on 14 December 2021.
As I reported previously, I opened a support ticket, spoke 4 or 5 times with an Apple support adviser, who emailed me links to data tracking apps which I installed on both my Apple Watch and iPhone, collected data during a 60-minute activity, and then uploaded these files to the Apple support adviser, who in turn forwarded these to Apple software engineers, who reported back on 30 December 2021 that these problems were indeed caused by a system issue.
This issue was known to Apple software engineers at least over 40 days ago, during which time Apple released 2 IOS updates without resolving these matters.
I was so concerned with this lack of resolution that I recently wrote to Apple CEO Tim Cook, email address tcook at apple dot com, on 7 February 2022 as follow:
(Please see additional text for content of this letter in the attachment below.)
I have not as yet received a reply from Mr. Cook, or from his staff.
I would suggest to anyone who is also experiencing these problems to (1) Contact Apple Support by phone or chat and open a support ticket in order to document the extent of these problems, and (2) Send a friendly email to Apple CEO Tim Cook. Mr. Cook reads many of these messages himself, and certainly his support staff reads all of them, collects issue data, and sets priorities based on the frequency of issues that are raised.
To insure that your concerns are heard, please be civil, polite and friendly.
Personally, if these issues are not fixed in the next month or so, I am going to return all of my Apple products to the nearest Apple Store ask ask for a full refund because both of these issues interfere with my usage and enjoyment of them, and also because my expectations in buying these expensive premium products was to have a more trouble-free experience.
I am relatively new in using Apple products, only since December 2020. Has Apple always had such issues with their products? I have read several accounts about Apple founder Steve Jobs, and believe that his drive for perfection would have caused such issues not to occur, or if then did happen, to demand that they were resolved immediately.
Thanks again for you comments. I hope this helps.
