We encountered a few issues from our update last night related to the email & mobile number validation. We have implemented a hotfix that will fix these issues and should allow things to work as expected moving forward.
Here are the details:
Email / SMS Validation: We've removed the Mobile Number Validation so the system will no longer check this. The system will continue to check the email formats to ensure that these are entered in correctly. If you have more than one email address for the Primary Email 1 field, then be sure to add a semicolon (;) to separate the two addresses.
NOTE: If the email field is left 'blank', the system will not try to validate this field.
