iCloud syncing issue on iPhone 16

[BHanular]

I have an iPhone 16 (not Pro) with IOS 26.1.
After the 26.1 update I noticed a red dot appearing on the Settings app. When I clicked on it I received the following notification:

Some iCloud Data
Isn't Syncing

When I clicked on it, I received the following notification:

Your end-to-end encrypted data stored in iCloud can't be accessed on this device. It includes saved passwords and data from Health and Maps. Verify your account information to resume syncing.
Resume Data Sync

When I clicked on Resume Data Sync, I received the following notification:

Couldn't Sync iCloud Data
To continue using iCloud to sync your end-to-end encrypted data, you'll need to delete current data stored in iCloud.
Cancel
Delete iCloud Data

I’m afraid if I click on Delete iCloud Data, I’ll permanently delete all my photos as well as all other data on my iPhone.

My iPhone photos are synced to iCloud.

Please review the attached images.

I would like to know how to eliminate the syncing issue and thus the red dot without permanently deleting the photos on my iPhone.
Any help would be greatly appreciated.

Thank you very much!

Often times you when you get that red badge message, it means you aren’t signed into one of the services with your account. Double check all the sign-ins with your account.

Thank you for the reply. That’s much appreciated!

I‘m signed into my iCloud account on my iPhone and iPad and they both have the same issue. That’s all the devices I have. Not sure what you mean by services.

Again, thank you for your attention to this issue.

Have you tried disabling Advanced Data Protection and see if the syncing issue is fixed? The only other thing I can think of is to try logging out of iCloud on your 16 and logging back in. Good luck with this issue, it can be nerve racking!
