For some reason the 3 and 4 finger gestures on my 2019 MacBook Pro 16" have stopped working. This happened for some reason with macOS 10.15.4 installed, and after upgrading to 10.15.5 they still do not work. Turning gestures off and on again doesn't fix it. Restarting the machine doesn't fix it.
This isn't just affecting the 3 and 4 finger gestures of my Trackpad, but the 2 finger double tap on the magic mouse isn't working either. Is there a bug in recent versions of macOS here?
What can I do to get my trackpad and mouse gestures working again? This is extremely frustrating!
