Just a quick correction to a typo in my original report. Incorrect code mentioned in the report: BGTaskScheduler.shared.supportedResources.contains(.gpu) Correct code used in my project: BGTaskScheduler.supportedResources.contains(.gpu) To be clear, my project code is using the correct static property. This typo was only in the text of my report. The underlying issue I reported still persists.

@DTS Engineer Hi Kevin, Thank you so much for the definitive and incredibly helpful answer. This clarification has saved our team a huge amount of debugging time, and we truly appreciate you sharing this specific information. That makes perfect sense and explains the behavior we were seeing. The main source of our confusion was the documentation, which lists both iOS 26.0+ and iPadOS 26.0+, leading us to assume iPhone support. Your clarification that it's currently limited to iPads with an M3 chip or better is exactly the information we were missing. Just one follow-up question for our team's planning purposes. While we understand this may not be formally documented yet, is there an official device compatibility list or a specific documentation page we should monitor for future updates on these hardware requirements? Having a definitive source to reference would be a great help for us as we define our feature set across devices. Thanks again for your help!

To be more precise, this reverting behavior doesn't happen 100% of the time, but rather intermittently. The Microphone Mode selection, for example, also sometimes fails to persist. There are times when I select "Voice Isolation" and the change is not applied, and upon re-opening the picker, the selection has reverted to "Standard".
