VedantKatekar Hey mate, please search the community and direct your comment to the relevant thread. Here’s some trips though
Check Background Running Permissions: In the CMF Watch app, go to **My** > **Background Running Permissions** and ensure that background running permissions are enabled.
In your phone’s system settings, allow high background power consumption for the CMF Watch app.
In the application and permission management section, allow the CMF Watch app to auto-start.
For Android users, access the multi-task management interface (swipe up from the bottom of the screen or press the button), and lock the CMF Watch app in the interface by selecting the top option.
Failing these I’d suggest you contact Nothing Support, state you’ve followed troubleshooting tips https://nothing.tech/pages/contact-support
