I have received an email message confirming my role has been set as a Designated Support Contact but I am unable to initiate a chat with support or open a support case.
Thank you for reaching out in the Community. Once added as a Designated Support Contact, it can take upto 24 hours for your access to get updated on the Community. I recommend reviewing this article for more information on this.
You should now be able to launch the chat and create a support case through the Case Portal on the Community. Please let us know if you are still experiencing the issues.
Remember to give Kudos to suggestions that help you!
