Cathy_Dew In relation to my post above. The new feature that allows Site owners to create their own themes and upload font packages imposes clear legal and compliance issues for our company and can not be enabled in our tenant (non-negotiable). It also completely destroys the ability to centrally manage any branding which completely goes against the centrally managing aspect of the new Brand Center (confused).
For everyone - this feature will be rolled out regardless of the Brand Center being enabled or disabled (what we've been told from Microsoft).
I've created a UserVoice for it (link below). This has already been raised with our corporate brand and legal teams to understand full implications. From our standpoint it needs to be disabled by default and us (your customers) to enable/disable as required.
