Missing the zoom scroll that was available in the program monitor - Premiere Pro

Hi @Priyanka26494747o2te, you can move around the frame when zoomed in with the middle mouse button or the hand tool (hotkey h by default).
Select the hand tool, then use the left mouse button to click and drag anywhere in the Program monitor and you'll be able to move around. You can do the same thing with any tool active by clicking and dragging with the middle mouse button, instead.
