Summary: I haven't made any changes to my system yet my trakt "collection" (now library) no longer is reflecting new items that I am collecting into Kodi.
Steps:
(1) Install trakt plugin
(2) Ensure that sync (one way, from Kodi to Trakt) is enabled with add new items to library checked
(3) Add items to Kodi
(4) Scan for new items in Kodi
Observed:
Kodi adds item, trakt indicates that it's syncing, but items don't actually sync and Trakt does not show newly added items in library.
Log attached.
