Mirror iPhone Notifications on Watch Not Working

• Apple Watch Ultra 2 (2024) v11.0
• iPhone 16 Pro Max v18.0 (upgraded/restored from iPhone 15 Pro Max)

I have my watch set to mirror notifications from my iPhone. basically, I have email notifications set to no sound. While these types of notifications are silent on my phone, they still are audible on my watch. Keep in mind that I do not want to silence my whole watch. I only want to silence mail notifications.

I have force-restarted both devices multiple times. I really don't want to reset my settings—as this will be a pain to reconfigure.
