Hello Chettytom,
Thanks for asking the Apple Support Communities for help with iCloud. Your link says waiting, I recommend checking these things first.
1. Verify your iCloud storage has enough space. This article will help, and states: Manage your iCloud storage - Apple Support
"If you run out of iCloud storage, your device won't back up to iCloud, new photos and videos won't upload to iCloud Photo Library, and iCloud Drive, other iCloud apps, and your text messages won't stay up to date across your devices. And you can't send or receive emails with your iCloud email address. If this happens, you can make more space."
2. If you have plenty of space, I recommend trying while connected to a different wireless network. You can also try by turning off Wi-Fi and testing only with your cellular connection.
- To turn Wi-Fi off and use your cellular connection, go to Settings > Wi-Fi, and turn the slider off. Be aware that this will use your cellular data until you turn Wi-Fi back on.
Thanks and have a wonderful day.
