Hello. I have an iPhone 16 Pro Max and a ChatGPT Plus subscription. Whenever I use the ChatGPT app in Advanced Voice Mode, my phone becomes extremely slow and laggy. It even stutters when I try to increase or decrease the volume, and the voice responses from ChatGPT also freeze or stutter during playback.

Is anyone else experiencing this issue on iOS?
