Web access to your data at iCloud.com

When you turn on Advanced Data Protection, access to your iCloud data on the web at iCloud.com is disabled to ensure that your data is available only on your trusted devices. If you turn on web access again, you can use one of your trusted devices to approve temporary access to your data on the web. Learn how to access your iCloud data on the web.

I made sure to disable advanced data protection again today, and everything worked perfectly this time. It seems like that resolved the problem for me! :)

Same issue with ADP on, and try to turn it off it work, but once it enabled it will not able to access from website.

I want to say they did some kind of change on the backend. Based off when this thread was created, and when the following article was edited, it makes me think they might've changed some thing earlier on January 5 or possibly January 4. I spoke with support and they are still investigating. They have not said if it's a known issue, but she said she is escalating it.

Something else they kept asking was, if I had a large amount of files specifically video files. I had two of the technicians asked me that. As far as I know, I don't have video files and iCloud Drive only in the Photos app, but it was working a few weeks ago and has been fine for a while now. You can try turning off, advanced data protection if you don't care about into end encryption, but I would prefer to keep advanced data protection on. Until they get it resolved. It has to be a bug of something they changed on the back end. Because everything was working fine with advanced data protection for months now.

Hopefully they resolve it soon.

This is sprouting up in many threads in Apple forums. Here is what I posted in one thread:

I've been storming LinkedIn and forums about Apple having this great product in ADP but no support for it.

I posted this:

Well, Apple fans (more so Advanced Data Protection users), Apple has done it again. ADP is, once again, broken.

There is NO consolation in the fact that the message shown to ADP users is different. Using an ADP protected app on iCloud now shows <App_Name? locked. For example, after trying to access NOTES and giving it permission with your iPhone, it shows:

Notes is locked

This application cannot be launched. Please contact customer support.

OK

OK? It isn't OK.

Forums are now buzzing with this issue:

<and I give reference to this forum>

and, once again, support is non-existent.

Apple has this great secure option called Advanced Data Protection but:

1. No one in Apple can seem to support it.

2. Apple seems to be in denial every time ADP is broken.

So, APPLE, please hear this.

Either DO NOT make Advanced Data Protection an option or FULLY SUPPORT it and have complete transparency when if and when it breaks.

Apple has always been known for stellar support on any and all it's products.

It seems that Apple has an Achilles Heel and it is defined by three letters:

ADP."

It's probably going to take Apple at least 2 weeks to quietly fix this until it breaks again.

DO NOT BE LURED into having any support person work on your device because it is NOT your device that is broken. It is the ADP back end.

Since the error message instructs you to, "PLEASE CONTACT CUSTOMER SUPPORT," I suggest you do that, rather than post to this user to user community forum. You can contact Support by tapping Support at the top or bottom of the screen.

What are you logging into when you get that message? iCloud.com/photos?

What browser are you using?

I believe it's due to advanced data protection, a new feature we weren't accustomed to dealing with before! I disabled it, waited, if you try login immediately after disabled it, I don’t think it will work! This is why I got the messages of errors asking to get support! There’s no errors just wait for it and it's working, for me everything is okay now :)

I thought I was the only one. Customer care said I have a problem on my end.

I recently reset my device on 5th thinking that caused this issue, after trying to login on multile devices, the same error persists while I can access everything on my iPhone with no issues.

Same error for photos, drive, notes, almost all the apps.

I have the same issue. It affects all data protected by ADP: photos, notes, reminders, files, and documents. I disabled, re-enabled ADP, changed recovery key to no avail. I have a case open with support atm.
