I don't know if this will help you since I have a Charge 4 and not an Inspire 2 but this same thing happened to me. I couldn't figure out how to get my weight to show up on the watch face tile. However, I figured out that it was showing my pounds gained/lost instead of my actual weight because I had set a weight goal in the app. Once I removed my weight goal, my actual weight is now showing on the weight tile on my Fitbit. Hope this helps.
