Follower interference:
The follower simply needs to be made so that it does not contact the latch at anytime. To prove this to myself, I marked the area of the follower that appeared in the latch window, then reshaped the upper portion of the follower and cut off a portion of the skirt. *If you are doing this mod to eliminate nose dives, you may not need to remove as much material as shown here. Try removing just enough material to allow the follower to pass the magazine latch without issue.
You can usually see where the latch is being scrapped by the follower.
Now, the follower does not contact the latch at any point. Magazine latch window (OEM follower on the left, modified on the right):

I might also suggest to check the orientation of the spring to the follower. We've had folks report receiving a new magazine with the spring installed incorrectly.
Correct position of spring on the follower:
