Hello @Grant Zhao,
Apologies for the delay.
Our engineering PG team has identified the root cause and deployed a fix to production.
I’ve just verified the consent screen by logging in with a personal Microsoft account, and the branding logo is now displaying correctly without any broken image issues. Please refer the below screenshot.
Could you please check on your end to confirm if the consent screen is now showing the expected behavior? If you’re still seeing a broken image, feel free to let me know, and I’ll follow up with the engineering team.
