My image credits reduce each month even if I don't use them. Is there a term that they are no longer valid?
I see you have an Adobe account with the same ID as with forums. I have checked your account and noticed that your image credits reduce because of the expiration of some of the previous credits. I would like to inform you,
What happens if I don’t use all my monthly licenses in a given month?
With a small subscription plan, which includes 10 images a month, unused downloads carry over to the next month as long as your subscription is active. The carryover limit is 120 downloads. With large subscriptions, which include 750 downloads per month, unused downloads do not roll over.
Also, you can use your monthly license as long as your membership is active, but you forfeit any unused licenses upon expiration of your subscription.
