I did what you told me to do. I was missing several episodes and I cleared the data. Now I’m missing everything even though I’m logged in to the trakt. I only have one series left. All movies synchronized, but the series didn’t. I’m sick and tired of this app bugging for almost whole month.
If you connect with Trakt shows are not added automatically (SeriesGuide would not know which ones). You can find a list of watched and collected shows on the discover screen.
