Hi everyone! I’ve been quietly following this thread as I’ve had the exact same issue since purchasing my iPhone 16 Pro Max. Today, I wanted to post an Instagram Story with some background music, but I encountered a bug where the song’s duration would consistently reset to 8 seconds, despite setting it to 15 seconds. I decided to delete and reinstall Instagram, and the music limit issue was resolved. Surprisingly, the phone has also become much more responsive when typing, and I haven’t missed any touch inputs since this morning (I live in Germany).
I’m not entirely sure if the two issues are connected, but I’m quite surprised by the improvement. My phone wasn’t performing well at all, even with iOS 18.1 RC. If you’re using Instagram, it might be worth giving this a try!
