Hi, NevilleGadd
Thanks for your post.
With the upgrade, to email address is now required. For an email address to be considered valid, you do need to make sure that you have an @ symbol and a domain address (i.e. gmail.com). For example abc@test.co.nz would be valid, xyz.ghi would not be (doesn't contain the @ symbol).
Please let us know if you require any further assistance.
If my response has answered your enquiry, please click "Accept as Solution" to assist other users in finding this information.
Best regards,
