I provided my son with an older iPhone5 cell. It runs iOS10 so it will run only 1Password v6. This is fine. However, our family account is with 1password.ca. While it lets him scan the QR code from another device, it refuses any attempt to login complaining about the master key/email address.
Since it doesn't show the my.1password.ca site upon scanning, is it possible the older version does not support .ca family account?
1Password Version: v6 last one
Extension Version: Not Provided
OS Version: iOS10
Sync Type: my.1password.ca
