What happens to Delta Drive and Delta Trust if a payment doesn't go through?
Short answer: Delta storage first becomes read-only — you can still download and restore — and the notice gives dates in advance for anything further. Paying restores everything straight away.
At first, nothing you'd lose: you see Payment didn't go through with Fix Payment, the same as for Storage Studio. Because Delta storage takes up space every day, its steps are stricter if the payment stays unpaid: it first becomes read-only — you can still download and restore, while sync, backups and sharing pause.
The notice always tells you in advance the date anything else would change — when it would lock, and later when it would be deleted. Paying before then restores everything straight away.
While your Delta storage is waiting for payment, Storage Studio itself isn't paused, because it's how you download and restore those files. See where your Delta plan and invoices are.
