It seems like quite a few of the GotG Pros that were just built are coming off the line with the magna grab not working correctly. I had two from the last run and neither would grab the ball when it was dropped out of the orb target lockup. Here's what it SHOULD look like:

If it DOESN'T do that on your machines, here are the things you can do to fix it so it works as intended:
1. Make sure the pitch is 6.5-6.7. The magnet is timed with how fast the ball should roll to be over the magnet. If it's too slow or too fast (PF too shallow or too steep), it will never grab the ball on the Orb exit.
2. Make sure your machine is absolutely level left to right with a real physical level (not an app). The apps can be quite wrong.
3. Put a slightly thicker post rubber on the post to the right of the target. This is so the ball will get a little more of a "bump" towards the left as it is released. Note the yellow post rubber I used (which is just was I had on hand) that gives the ball a nice bump to the left when released.
4. Take the magnet bracket off and insert 1 or 2 washers (experiment) between the bracket and the magnet core to raise the core so the core is lifted to touch the playfield underside and eliminate any gap. This is the fix Stern tech support has recommended for people having trouble with the grab. I have done two washers on the two GoTG's I've done, but the gap you're trying to fill varies, so it may be different for yours. The area where the ball should be grabbed (using the PF art for reference) is the bright spot just above the tip of the hammer.
