“Cannot Complete Action” when trying to accept new iCloud Terms & Conditions on iPhone 14 Pro, iOS v17.6.1

I had the same issue today. Just got off chat/ call with Apple Support. They were great. The problem has been resolved. So, we did two things, I updated to iOS 18.1, but I also delegated my VPN app from my phone (I can reinstall it if I choose.) So, I’m not certain which of the two variables did the trick. The VPN app caused the update to run slowly. Tech said it may also have interfered with the privacy security of the iCloud T&C acceptance process. Regardless, it is resolved. Apple Support was such a positive experience.

Ditto the problem. Updated iPad Mini to OS 18.1 (no hiccups) and could then click on the “Continue” without the negative message appearing. Would have been more helpful if Apple had displayed a message like “Please update your software to the latest version” or similar.

Upgraded to 18.1 without deleting Wireguard. All fine afterwards.

I cannot upgrade to iOS 18. I’ve an Xs. I’ve had the ‘Cannot complete’ for a week now.

Thank you for your quick reply!

I'm using Wireguard myself.

I'll try uninstalling and see if that helps

Have you upgraded to iOS18.1? If not, be sure to delete the VPN before that download. (Sometimes shutting the VPN doesn’t really shut it down, delete it from the phone .You can restore it when the update is done.) If this fails, go on with Apple support. I started a chat and they moved my issue up to a phone call. Soooo helpful!

You might go to Support.Apple.com and look at “How to download iOS 18”. It has the iPhone XS listed as compatible. It gives info there on how to download and install the latest update. If that doesn’t help, you can start a chat at Apple Support. They helped me. Good luck!🍀

Hello @mamapix what VPN app was that ?

Good luck!🍀

I just uninstalled Wireguard, shut down my phone and powered it back up.

Still the same error in my case. Will do some more testing.
