Why can’t I use the AI assistant on Nothing headphone (1)?

Nothing products aim to bring fun and smart technology experiences. The headphones’ support for ChatGPT requires the following conditions: 1. This feature only works with Nothing phones running the latest system version. 2. You need to update and use the latest Nothing X app from the Google Play Store. 3. You must download, install, and log into the ChatGPT app from Google Play Store, and use the ChatGPT Voice function at least once. 4. In the Nothing X app, go to Controls, then set ChatGPT as the action for Single Press or Press & Hold gestures and apply the setting. Please check if all these conditions are met. If the issue persists, contact Nothing Support for further assistance.
