I'm trying to change the Asset settings to my organizational account and I can't find it (In the Admin Console, navigate to Settings > Asset Settings.)
Can you please advise what can be the problem?
What type of an account or plan do you have? This fuctionality is available with Creative Cloud for enterprise plans. From the screenshot it seems that you might have a Teams plan and so this functionality is unavailable. (You can check for your plan type in the Account tab.)
