Additional Problems with Device Synchronizationin in Version 6

After an initial burst of activity catching up numerous synchronizations and the appearance that new updates were being reflected in a reasonable amount of time on secondary devices, something has changed. Now, new episodes marked as watched and some changes to personal lists are not being reflected on a secondary device in a reasonable amount of time. I have several examples. I have marked as watched several new episodes of “Dexter: New Blood”, “Dexter: Resurrection”, “FBI”, “NCIS”, and “NCIS:Origins”. None of these are showing up correctly on my secondary devices. In addition, changes to my personal lists are not being updated on the secondary device properly. It looked as though this had all been fixed, but now it’s back to not working.
