Expected behavior is to see a 1-2 day delay in used savings plan data in Cost History.
There are two common reasons to still see unused Savings Plan data if the delay is more than 2 days:
1. Confirm in AWS console that Savings Plan data is indeed used.
2. This is likely due to a delay in our data processing. This can occur and autocorrect itself.
3. Due to an ongoing data incident. Please visit the service status page for more details. https://status.broadcom.com/
