Smooth scrolling not working with Magic Mouse and macOS Catalina 10.15.3 Recently, smooth scrolling has stopped working on my MacBook Pro when scrolling with the Magic Mouse. Using the internal trackpad works fine and smooth scrolling behaves correctly.

I initially noticed this behavior in Chrome but it appears to affect all apps, including native ones like Pages or Safari.
I fixed this by deleting the mouse from Bluetooth settings, and then pairing it again using a lightning cable.
