Input System no button press when timescale = 0

Simply put, hitting the menu button sets Time.timeScale = 0, and the game pauses, but nothing can unpause it or happen during the period. The Debug statement gets called the first time, and then nothing.

     private void TogglePause()
     {
         Debug.Log("Pause was hit");
         isPaused = !isPaused;
         if (isPaused)
         {
             AudioListener.pause = true;
             Time.timeScale = 0;
         }
         else
         {
             AudioListener.pause = false;
             Time.timeScale = 1f;
         }
     }

Any reason why the new Input System would not receive/send InputAction.Performed?
