Disclaimer: I'm not a beta user, so I have no idea if I'm telling you something you already know, but are you going to System Preferences > Apple ID > iCloud to look for it? (see screenshot from what I found here). If so, then have you tried 1. restarting your Mac, or 2. signing out of iCloud and then signing back into iCloud?

Yep. tried a bunch of times. Restarting, fiddling with my network etc.
At last after about a week it turns up right as I get this reply!
Thanks. Leaving up here for anyone who has same issue.
