I am using this App on my NVIDIA Shield 2017 , I use Cyberflex type apps to watch TV. We view a lot of series shows. I have everything connected such as Trakt TV along with extensions. After an episode I hit the update to Trakt TV within Cyberflix . Is that supposed to update my favorites within Series Guide by checking that episode as watched, because it is not? Also if not, then what does syncing do besides sync between other Cyberflix type apps, Trakt TV and devices?
