Bug : Mask Tracking for Premiere Pro CC 2019 is not working fully.
The tracking begins and stops and stalls sometimes as well not tracking at all.

In the new version of Adobe Premiere pro 2019, when I click on the tracking button it does not show the movement of the mask
I have to pause the tracking to see its changes! What can I do?

I'm having difficulty as well and it is preventing me from completing a project. My footage is 4K, 4096 x 2160, 24 fps. The object I am trying to isolate via masking is slow moving and not complicated. When I click Forward on the Mask Tracking bar, I get a tiny amount of progress and then it stalls, and for hours, I get nothing more. Nothing happens when I try to do it frame by frame.
I'm having the same problem - with very simple, slow and easily distinguishable foreground/background footage. Very frustrating - I can't finish my project

I am running into this problem right now as well. I have a 4k mp4 clip just pulled of my Sony A7S. I've added the lumetri effect and just drew a rectangle over the area I want to track. The movement is a very slow and controlled dolly move on an object. It should have no issues tracking this. After multiple attempts, the mask will not track across the footage. In fact, once the "Tracking... progress" bar shows up, it doesn't actually make any progress at all.
I've deleted the effect and reapplied. Also tried tracking in different directions, etc. Just sits there. This has worked for sure in the past, but not in this most recent version at least. Currently running 13.1.5 on an iMac Pro.

I'm having the same problem. Clear difference between subject and background.
Everything is up to date (latest version to this date).
If I press play or use the button to go frame by frame ... the mask either stays still or it flips in the weirdest way possible
Mine doesn't work at all, when you hit the play button or frame by frame button nothing happens. I would like to inform Tim Cook I won't be buying a $8000 Mac Book PC so this fancy GPU tracking effect works properly. Adboe make software that is compatible with lower grade graphic cards.

Same problem. I applied the Leave Color effect and masked a portion to be affected. Screen shot shows the progress made before the tracking stopped — for the third time.
@Francis Crossman: Using Premiere Pro 13.1.3 (Build 44) on macOS 10.14.6. My footage is from Adobe Stock: H.264, 1920 x 1080, 25 fps. Tracking should be easy because the area being masked moves only slightly during the clip. You can find the same clip on Adobe Stock by searching for 203906961.

Same Problem, just spent an hour masking a transition and the mask appears about 15 pixels after where it's suppost to be. Like if i added mask expansion but i didn't. Could you please help me i'm getting crazy.

I'm having the same issue.
Sorry to hear you are having problems with the mask tracker. Can you please provide more information about the footage you are trying to track? It's useful to know the resolution and framerate, but most importantly - what's going on in the scene. Mask tracking technology does not do well with fast-moving objects (lots of motion blur), when the object goes off screen, or when the object is occluded (some other object passes in front). Mask tracking can also be thrown off by wildly changing lighting. Do any of these situations describe the footage you are trying to track? Remember that at its core, mask tracking is trying to lock onto a pattern of pixels (usually several patterns) and find that same exact pattern from frame to frame. If the pattern is hard to find (motion blur, lighting) or disappears altogether (occlusion, goes off screen) then the tracker will likely fail.
