Yup, this update wrecked a lot of people's HDMI-CEC. Mine is just CEC using a direct connect to a Hisense TV, will not see the Hisense remote anymore. My friend has his connected through his receiver, and same issues
Apple is aware... 17.4 messed up HDMI-CEC connections with receivers with third party remotes, ie: Samsung Smart and other remotes. Unable to use remotes to control Apple TV4K.
This latest 17.4 update rendered Crestron control inoperable. Apple needs to push another update out soon to repair the damage that this update caused!
There is about a one week delay on them, alerting you that there is a update. The reason for this is to prevent system breaking or other software issues from spreading so fast.
This I am unfamiliar with. My experience has been sometimes it takes a long time to progress, but it does progress. Thanks for watching and share if you ended up getting it to progress.
Have it turned on for all my Apple devices ,never get a automatic download overnight, never get a notification there is a update or that a update is available . Why do they have it ?
I follow 1 rule with apple, never update if it is not broken, they deliberately break functions using update, and shortly after that release a new product to fix.
