My Workspace account's profile picture not shown to Gmail recipients

My Google Workspace account profile image isn't displaying to Gmail recipients.

1. I followed the instructions from Control what others see about you across Google services for my Workspace account.
2. In About Me, under Basic info > Profile picture, I confirmed the visibility is correctly set to Anyone.
3. When I send an email from that account to my personal Gmail address, I still don't see the profile picture, instead my first initial in a solid-colored circle is displayed.

What should I do to have my Workspace account's profile image displayed to Gmail recipients?
