Reminders not syncing on Apple Watch

After installing the recent Apple Watch update, my watch no longer syncs Reminders. When i go to create a reminder, Siri’s response is “I didn’t find a ‘Reminders’ list. Do you want to create one?” I’ve still got all the same one’s I’ve ever had on my phone and iPad. But no such luck on watch. I’ve been creating reminders this way on my watch for years. I use this feature many, many times throughout the day. How to resolve? Dredging the support archives, I’ve restarted watch, phone, checked iCloud settings, created test reminders and lists. Any other possible fixes?
