My Apple Magic Mouse 2 connected to my Mac via bluetooth has stopped working, battery status is also shown but neither cursor or buttons and gestures are working. I have tested on my Windows 10 PC where I am able to move only the cursor but the buttons are not working. I tried out some repair steps which I find online but nothing works. Please Help!

This mouse still uses a physical switch for the click. Whats likely happened is the battery has swelled up pressing on the upper case so the control is messed up. You’ll need to open it up to replace the battery. Here’s the guide Magic Mouse 2 Battery Replacement and here’s the battery Apple Magic Mouse 2 - Internal Battery and Lightning Socket
