My pricing localization changes won't apply to my pricing table

You've been trying to localize your pricing to a certain country by passing billingCountryCode but the result is not displayed on the pricing page. In that case, it is possible that you have overwritten the text using Text Overrides.

Text Overrides allow you to customize the default text when setting price localization.

To revert that, go to textOverrides and make sure that doesn't have a value overriding the default text.
