Have you checked your Email headers for DKIM Failure?

Have you checked your Email headers for DKIM Failure?

Have you taken a look at your email headers for DKIM failures even with DKIM set up properly?  
  1. I've had DKIM successfully set up for many months.
  2. My account currently shows Email Verified and Authenticated. Big green check marks.
  3. Email Relay is also showing DKIM Authentication Validated. 
  4. We use Google Workspace for outgoing mail.
Yet, when I review the email header sent to one of our test accounts, DKIM Failure.

Can anyone else check and see if they have the same problem?  (Look in the detailed email header)

Zoho support has been sitting on this for 13 days with no solution or fixes. (We know how Zoho support is, I am assuming someone is actually looking into it.)

Thanks
