Overview of the issue

For websites hosted on Kinsta, there may be instances where WooCommerce Multilingual currency switching functionality encounters difficulties. This can result in users viewing incorrect currency displays or being unable to switch currencies as expected.

Workaround

To mitigate this issue, a combination of code adjustments and Kinsta support intervention is recommended.

  /**  * Enable cookie strategy for Kinsta caching.  *  * @link wpmlsupp-11434  */ add_filter( 'wcml_user_store_strategy', function () {     return 'cookie'; });

Step 2

After implementing the code snippet, reach out to Kinsta support to request enabling cookie-based caching for your site. Specifically, ask to use the wcml_client_currency cookie for cache bucket keys.
