Copilot is not applying the brand kit as expected

When I use the Create function in Copilot, the Brand Kit I set up is not applied correctly. For example, when generating a video and prompting Copilot to use Brand Kit assets such as logos, fonts, icons, and colors, those elements were not reflected in the output. I would like to understand whether this is due to an issue with how I am prompting, or if this is a current limitation of the tool, so I can better ensure output quality. Additional details are provided in the attached document.

Example Prompt: Create a dynamic, high energy 30 second promotional video showcasing the Learning Design System (LDS). Start with fast, clean motion graphics introducing the concept of "A smarter way to build learning materials" Show modular, animated UI components assembling together like building blocks. Highlight keywords with bold kinetic text: "Reusable Components," "Clear Standards," "Consistency," "Efficiency," and "Engaging Learning Experiences." Show visual metaphors of harmony and collaboration—smooth transitions, synchronized motion, and shapes locking into place. Display learners interacting with sleek digital interfaces, simulations, and microlearning modules built from the system. Use appropriate brand colors, modern gradients, and subtle technological textures.
