Apple users have been facing issues with the iCloud account on different devices. Many users on Apple’s forums also complained about certain sign-in issues on HomePod and Apple Watch. I got my two kids (<18 yo) Apple Watch SE + Cellular, with plans to activate via Family Setup/sharing. Apart from issues on the Apple Watch products, many users also complained about a similar issue while logging in on their HomePod. The users complained that they were not able to setup their new device due to the issues.
