Hi @carl.t.
It looks like you do not have a Passwordless SMS connection. Looking further, I noticed your users have their phone numbers saved to their user_metadata.
When updating the user’s phone number in the user_metadata, it should not alter the user’s display name or change their email to their nickname.
If this is happening, you could workaround by updating the user with the name or email value of the preferred value.
I hope this helps!
Thanks,
Rueben
