I updated my iPhone X and Apple Watch Series 4 to the latest iOS and watchOS releases (13,6). Since doing this, I cannot see Reminders on the Watch even though they are visible on the iPhone. Is anyone else seeing this?
UPDATE: My reminders just came up on my watch! The unpair/pair seems to have worked. It took a while to load but they are now all visible. Whew!
9/25/19 - Yep! Me too. Same scenario: iPhone X and Apple Watch Series 4 to the latest iOS and watchOS releases (13,6). I resynced and unpaired/re-paired. Still the basic reminders "folders" show: Today, Scheduled, All, and Flagged. None of the Reminder lists I have on my iPhone.
I found a much easier fix for this problem than unpairing and pairing.
I merely went to the iCloud settings on my phone, went to Reminders, and turned them off. I then deleted them from my phone (as the server-side version was correct), turned Reminders back on, and after they appeared on my phone, they also appeared on my Watch.
Was in this same situation for a few days on non-beta versions of each. Solution for me was to open Reminders both in the watch and the phone at the same time and wait about 30 seconds. There seems to be a bug that requires it to be open on both sides for the initial sync. Hope this helps and good luck
