I would like to buy a font license.
If we buy it using the Team Administrator account, would it be accessible for all the members in our team?
Fonts you buy from the Marketplace are single-user purchases; the fonts will be added to your Adobe Fonts account (Adobe ID) that is used for the purchase. If everyone on your team needs the same fonts, they would each need to buy those fonts on their own account.
I hope that this helps! Best,
