Controlling timeline using Unity Playable Controller not working properly

Unity version: 2022.3.34
Mesh toolkit version: v5.2314.130

Hello, as the title says I would like to control a Unity timeline using the Unity Playable Controller from Mesh. However, after adding the component and linking up the playable director as instructed in the doc and doing a test event, the controller doesn't seem to work. The animation doesn't pause when the pause button is pressed, and when I resume the animation snaps back to the point in the animation where it should have paused. 

For example;

A cube moves from point A to point B in the animation. I want to pause the animation (stop the cube from moving at its current position) when the cube has covered 50% of the distance by pressing the pause button, but the cube continues moving towards point B when doing so. When the cube has moved 75% of the distance, I press resume in the controller, and the cube snaps back to the halfway mark between the points and then continues. 

Is there a setting I have missed or anything else that might be causing this?
