Magic mouse 2 moving slowly, jerkily, and causing 'shake to locate' to activate all the time
I just charged my Magic Mouse and am using it for the first time in a couple of months, and it's behaving very weirdly. The tracking feels very slow even though it's on the fastest setting, the pointer isn't moving smoothly and the 'shake mouse pointer to locate' thing is turning on all the time (obviously I can turn this setting off, but I feel like it's indicative of the issue with the mouse's tracking). I've tried restarting it and my mac, and cleaning the sensor with compressed air.
Here's a screen recording:
Any other ideas??
