ZOHO Flow suddenly generating CORS errors

ZOHO Flow suddenly generating CORS errors

We are writing an application that as of yesterday stopped working since our JavaScript calls to ZOHO Flow have all suddenly stopped working.

The error is the dreaded CORS error:  has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Is anyone else suddenly having this issue?
