I am trying to manually unhide items from Hidden on Trakt website, which works, but the next day I log in I see again everything back in place (= hidden). There’s no app synchronizing with my account, hence the scenario when it has overwritten my work is not possible. Why may this happen?
And finally - is it possible to mass unhide items? I have several thousands of them - really boring to click each single item.
First, I recommend you to clear your browser cache at: Advanced Settings - Trakt
Just to make sure that isn’t a visual bug.
If that continues to happen, please send an e-mail to support@trakt.tv since it could be an issue to your account specifically. Also ask about the mass unhide items there, there is no native way of doing that, but I’m not sure if the developers can do that for you.
