Office 365 Branding not applying

[blu4]

Morning,

 

I want to add some branding to the "stale" office 365 login page. I go via the Admin centre to Azure AD -> Configure -> Customize Branding. I add all the necessary files and I get green ticks when it's done. Issue is that it's not showing when I type in my login or whenevery I go through this link directly to our organization https://login.microsoftonline.com/?whr=yourdomain.com (I do replace the yourdomain with my domain, duh!)Do I have to wait some time for this to apply or should it be instant?

Cheers

 

EDIT: Just had to wait 10 minutes. It's working now.
