  - Block a frame with origin "https://<customer unique id>.launchpad.cfapps.ap10.hana.ondemand.com" from accessing a frame with origin "https://my<customer number>.s4hana.cloud.sap.com". Protocols, domains, and ports must match.

NOTE (Root Cause) : The issue tied to the origin domains above: "ondemand.com" and "cloud.sap" is marked that it should match.

Follow the following recommendation steps in order:

1. Switch the operation of your SAP Build Work Zone, Standard Edition subscription (including the Onboarding to SAP Mobile Start) to the SAP Common Super Domain (cloud.sap). The following (SAP HELP documentation) https://help.sap.com/docs/build-work-zone-standard-edition/sap-build-work-zone-standard-edition/using-super-common-domain?locale=en-US describes how to access your SAP Build Work Zone, standard edition site with the cloud.sap domain. Please note that the ondemand.com domain stays active and users are not redirected.
2. Kindly ask your users to re-onboard Mobile Start via the QR Code shown on Work Zone Standard when it is being accessed via its cloud.sap domain. Alternative you can push the required configuration to managed devices using an MDM solution.  See documentation: https://help.sap.com/docs/mobile-start/mobile-start-administration-guide/mobile-device-management-mdm?locale=en-US
3. Make sure that all you integrated Cloud Content Providers are operated under the same common super domain. This is also stated in the documentation (https://help.sap.com/docs/build-work-zone-standard-edition/sap-build-work-zone-standard-edition/content-providers-cloud-solutions?locale=en-US) of SAP Build Work Zone, standard edition: "For integrating content from cloud solutions, all systems must operate under the same domain."
