Candidate getting warning "Preferred Communication Channel Doesn’t Exist", not receiving any message

Summary:

Candidates applying through the career site see a warning message stating, "Preferred communication channel doesn’t exist." This is preventing candidates from receiving messages via email or SMS.

As per the standard process, the communication channel (email or SMS) used by candidates during their initial authentication on the career site is automatically set as their preferred communication channel. This channel is then used by default for all recruiting-related communications.

Since candidates are applying via the career site, they must have used either email or SMS for their initial authentication. Therefore, this warning should not appear for either communication channel in these cases.
