Quick answer is no, Track did not show the parade. They had a camera placed at each of the 4 mats. If you had the cameras on you could hear them making the announcements during the parade and see kids as they walked by and eventually stopped in front of said cameras, but it was not intentional coverage. It's my understanding that Track provides an event kit which includes the cameras, etc. but it is not a true broadcast in the sense. Hell, mat 3 only worked about half the time and mat 4 had no sound. I don't know if that is on Track or who is responsible for executing it all. No announcers on 4 irritated me, but not as much as mat 3 freezing repeatedly.
The other thing that pissed me off about Track is they no longer allow streaming/casting from multiple devices at the same time. I tried to cast one of the mats to a 2nd tv and couldn't do it. Couldn't do it from a new browser window (tried incognito one as well), and tried from phone/tablet. As soon as I would cast to the 2nd screen, it would be gray and do a :30 countdown. A soon as that cleared and video came up, the other cast/TV would go gray. Couldn't do both simultaneously. In the past, I could watch two mats on two TVs and a 3rd on my laptop. This year, I could get all four mats on separate tabs on the laptop, just had limits on casting to TV's.
