It's seems odd, but it only occurs when you're first signing in a device to an Apple ID, either during setup, or once the device has been setup and trying to add the iCloud account later. So generally day to day most people wouldn't even notice. I had issues with a new device last week that utterly refused to verify to Apple connected directly to the Sky hub, it worked OK with my non Sky mesh even though this still used the Sky connection. Another device today just refused even via my mesh, but because I'd already hit the issue last week, I just hotspotted to my phone, connected the device to the Apple account, then dropped it back on the mesh and everything else works fine. I do Apple support, so its the kind of issue I suddenly notice more, hence here wondering am I alone in the issue, but clearly not...
