Hi,
i have a Problem with it Seen/Unseen feature for YT Videos, again. 
But a little different this time. Videos with i have seen are marked as seen, but videos witch i have starded but not finished, are not marked as those only as unseen. Still i can “resume at xx:xx”.
This happens only in YT, media libary and Twitch are fine. (I dont kown if the twitch plugin supports this new policy form team kodi for the seen/unseen feature.)
MfG
