iCloud Advanced Data Protection - Can't Activate

So I get through the activation process for ADP up to the point where it gives me the 28-digit recovery key and then asks for me to type it back in. When I either type or paste in the code, it tells me that verification failed. Anyone else having this problem?

Have you updated ALL your devices to the new systems yet? My understanding is that you have to do that before ADP can be activated.


I did not know that! Thanks so much for the tip!

Still no luck. Upgraded all my devices that were listed in my iCloud account. Looked in iCloud to make sure they were all listed and that their upgrades to the newest OS were shown in iCloud. Restarted my phone just for fun. But no matter what I do, all I get is:

Same thing here with my wife’s Apple ID. Mine worked fine.
