When your BTS light stick doesn’t sync with the app, it might be because your Bluetooth is not turned on or not connected properly 📱.
This can also happen if your app is not updated to the latest version, so make sure to check for any updates in the app store 📈.
Another reason could be that your light stick’s battery is low, so try charging it and see if that solves the problem ⚡️.
If none of these solutions work, you might need to reset your light stick by pressing and holding the button until it turns off, then try syncing it again 🔄.
Lastly, ensure that you are using the correct app for your light stick, as different models might require different apps 📊.
