Random Thoughts

Well I fixed the bug! The issue was the sequence of the code sequence between the ContactPicker and VStack within the Navigation View. I hadn’t realized that this was issue (Obviously). Here’s a video of the real way it should work.

As you can see the UI is now working as you would expect.
