iCloud syncing issue

[BJH]

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 saved to iCloud.
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!

You can try signing out of your Apple account and then back in again. That sometimes forces everything to reset.

If you go to Settings/Your Name/iCloud, you will see a list of items that are saved to iCloud. You could try turning them off individually from there and see if that isolates the problem.

I can't help with iCloud Photos because I've never used the feature.
