According to this weeks fortnightly (because it's been two weeks since the last one) update "Storage usage in Creator Studio. A Storage page under Analytics, and a card on the dashboard, show what you're storing across model files, training data, 3D files, attachments and media."
I've looked everywhere in the creator studio for this display and it just isn't there. It's not on the dashboard.
It's not under analytics in the side panel.
Did we wait two weeks for an update just to have features hallucinated at us?
3Hours after the update the Creator dashboard was updated to bring it inline with the claims from the site update.
