iCloud selective sync setup idea

My AppleID is used with the main AppleTV and I would like to keep Up Next separate between the shared TV and my other devices. I thought I’d just turn off iCloud sync on the AppleTV but I’m concerned what features I might miss. In the iCloud Sync Support Article it lists a number of features and I hope some of you could clarify some finer points about the watched history. I thought that is done via the Trakt account that I’m logged in or is it simple referring to Infuse’s built in watched history feature only and Trakt would still keep my watched history in sync across all devices that I am logged in with.

I hope there is a simple answer to this :slight_smile:
