@Engineer It’s on iOS 26 (the screenshot was back even I had iOS 18 installed, though) And yep, the rest of the devs are aware :) but it doesn‘t appear to be an issue on our end (Android’s not having a problem reading the appearance characteristic). I should also mention that reading directly from appearance characteristic via CoreBluetooth results in undefined. The Feedback ID is: FB20117783 Thanks for your help!
