in version 6, it does not appear that changes are being synced across devices. I have 3 devices signed in with the same iD. I have marked several episodes as watched on my primary device, and the changes are not showing up on my other devices.
How long did you wait? Did you try to trigger the fetching, like opening the list or pull refresh?
I waited several days.
Yes, I went to the other devices and did detailed displays of the shows with the updates. On the season lists, none of the added episodes were marked as watched. The syncing on these devices always worked fine on version 5 with no intervention from me. It just looks like syncing isn’t happening at all.
Also, on version 5, I would often see my personal list icons (the background images on the home screen) flashing when a sync was in progress. I haven’t seen that once on version 6.
