Why is not my catalog rule applied after the «Save and apply» button click?

Hi.
I have a question. How long catalog price rule are applied?

Steps:

  1. Add a new catalog price rule.
  2. Wait some minutes while rule is applied.
  3. Then Update this rule and click ‘Save and apply’ button.
  4. But on store front nothing update.

I was waiting for 10 minutes, nothing update, clean cache and nothing update.

Then I deleted this rule, cleaned cache, was waiting some minutes, opened storefront and saw that my rule from second step was applied but I deleted it.

Can you tell me, why it’s working?
Thanks.

The «Save and Apply» button click applies the rule instantly, so you have just misconfigured the rule.
