MX Master 3 has bluetooth connectivity issues with MacOS12 and Creative MOVO Play speaker. When both devices are connected to the Mac, the audio output of the speaker is disrupted. The sound is not smooth and lags/stutters. The problem is can only be resolved by either disconnecting the bluetooth connection between the mouse and the Mac, or switching off the mouse entirely. On USB receiver, this problem does happen. Both speaker and mouse work fine.

This problem happens to MX Ergo as well.
