Hey! When you upgrade your plan, your old subscription is automatically canceled, and you’ll get a prorated refund for the unused time. In your case, you’ll get a refund for the remaining 1 day of the Pro plan.
Please note:
- The refund can take a few days
- After upgrading to Pro+, you can’t automatically go back to your old plan, you’ll need to start a new subscription
Alternative: if you only need extra credits for one month, you can use on-demand usage without changing your main plan.
