Issues configuring iPhone with iCloud

On the overview page I get box informing me I need to configure my wife’s phone, I click the configure link and the below dialog pops up

iCloud eapple
Please choose your trusted device by entering the index from this list: 0: SMS to ******** 19;
Trusted Device

I enter 0 and click confirm, nothing seems to happen, looking at the log below I see the following error

Error executing service <ServiceCall configurator.configure (c:3ee3f38bb77a48e38adcd505a688bf09): configure_id=1879764784-1, fields=trusted_device=0>

IndexError: list index out of range

This is what I’ve done each time wife has changed her password, and every other time it’s worked. Any help would be greatly appreciated.

After applying a new update everything started working again, and wife’s phone is reconnected.
