Shared lists always share the list’s items. Syncing is an optional, separate feature that can also synchronize watch progress and TV scheduling across collaborators.

When someone adds or removes a title in a shared list, the list contents are updated for everyone who has access to that list.

Permissions still apply:

• Collaborators can edit list items.
• Viewers are read-only.

Read: Manage Collaborator Permissions.

The list owner can enable:

Sync watch status & TV schedules with collaborators

When enabled, WatchThis syncs progress for titles that are in that specific list, including:

• Overall watch status (Planning/Watching/Completed, etc.)
• Episode watched/unwatched progress for TV
• Weekly schedule selections for TV

Sync applies only to titles that are included in the shared list with syncing enabled.

• If a title isn’t in the list, syncing won’t happen for that title.
• If you remove a title from the list, future progress changes won’t sync via that list.

• Sync is designed for “watch together” lists where everyone wants the same progress.
• Updates are not instant messages; collaborators may need to refresh or revisit a page to see changes reflected in their UI.
