I have set Ear (a) to use gestures for volume control. Why can't I adjust the volume through gestures?

Due to compatibility issues with Bluetooth protocol versions of devices, some phone or computer models may not support the volume control protocol. This issue could potentially affect TWS Bluetooth earbuds. If you encounter this issue, try connecting the earbuds to another commonly used device to adjust the volume. If the issue doesn't persist, it means the device, not Ear (a), needs checking.
