Prices flickers on the product page

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is experiencing an issue where the prices on the Swedish site flicker between SEK and DKK. Initially, the SEK price is displayed, but it quickly reverts to the default DKK price.
Solution:
The issue is likely due to the use of the 'WooCommerce Extra Product Options Pro' by 'ThemeHigh', which is not officially compatible with WPML and WPML Multilingual & Multicurrency for WooCommerce. We recommend discontinuing its use or contacting ThemeHigh for support. Alternatively, we suggest using one of the following officially compatible plugins to ensure stable currency display:

robinK-18	Background of the issue: I am trying to show local prices on different domains using WPML. Our default domain is dolk.dk with currency DKK. When I visit the Swedish site dolkoutdoor.se, I expect to see prices in SEK. Here is the link to a page where the issue can be seen: hidden link. Symptoms: On the Swedish site dolkoutdoor.se, the prices on product pages flicker. Initially, the SEK price is shown, but after a few seconds, it reverts to the DKK price, which is the default. I expected to see the price as Before price: 509,54 kr. Current price: 392,74 kr, but instead, I got Before price 349,00 kr. current price: 269,00 kr. Questions: Why are the prices flickering between SEK and DKK on the Swedish site? How can I ensure the prices remain in SEK on the Swedish domain?

robinK-18	Hello. It appears that the issue is an incompatibility with "WooCommerce Extra Product Options Pro". Can you please assist in fixing it?

Itamar WPML Supporter since 02/2016 Languages: English (English ) Timezone: Asia/Jerusalem (GMT+03:00)	Hi, The 'WooCommerce Extra Product Options Pro' by 'ThemeHigh' is not officially compatible with WPML and WPML Multilingual & Multicurrency for WooCommerce. You might face problems similar to those you experienced with it. I can see on their website that they state for compatibility with WPML: hidden link. Please understand that we can't be responsible for what they state. If you want to keep using it, please get in touch with them for help with this issue. Alternatively, please consider using similar officially compatible plugins like the following. https://wpml.org/plugin/extra-product-options-and-add-ons-for-woocommerce/ https://wpml.org/plugin/flexible-product-fields/ https://wpml.org/plugin/product-addons-for-woocommerce/ Regards, Itamar.

robinK-18	Sounds like we need to use a plugin from your list.
