Yes sure. I actually have one more suggestion for you - try removing and then reinstalling the Camera Remote app.
You can remove it from the watch, either using the grid (press and hold) or list view (right swipe). To install it, open the Watch app on your iPhone, tap Discover and Explore Watch Apps. Search for "Camera Remote" and scroll down for the Utilities entry by Apple.
If that doesnt fix it, here is some additional detail of the backup that will be taken when you go thru the unpair and re-pair process. Almost everything is taken care automatically, but for security reasons Apple Pay will need to be set up again.
