iPhone, iPad and Apple TV seem OK after the updates.
It is irritating that the setting for automatic updates is turned on after this update. At least there was on obscure alert about this during the process. Also the update nagged me to turn on Siri voice activation, which I never want. The only suitable choice was “Set up later” so I guess the nagging will return.
BTW - my iPad battery was draining very fast a couple of days ago. I read somewhere (maybe Tidbits) that some apps chew up battery if Background app refresh is enabled. Annoyingly I found that nearly all my apps had it set to “on”. I switched nearly all of them “off” and the battery issue has gone.
I hate it when the software decides these things for me!
