Unable to reclaim Storage for Actions and Packages after deleting all files

Question

When i try to run a github action (it will build android apk) it showing an error

You've used 100% of included services for GitHub Storage (GitHub Actions and Packages). GitHub Actions and Packages won’t work until a monthly spending limit is set.

So i delete all Artifacts files but after i delete each Artifacts the Storage for Actions is not reducing
For example i delete 20 Artifacts file and each contains 20mb. Which means 400Mb and when i check the "Storage for Actions" it is still showing it is overflowed
Why this is happening?

Answer 1

I encountered an identical problem. After looking at the docs, it seems it takes one hour for storage usage to update.

From the documentation:

Storage usage data synchronizes every hour.
