Add-on percentages converted

Hi,

We are currently evaluating your currency switcher plugin, which seems to meet our needs overall. However, we have encountered an issue with its compatibility with the WC Product Add-Ons (https://woocommerce.com/products/product-add-ons/). Specifically, add-ons defined as a percentage change to the price are being scaled according to the selected currency. For example, an add-on that adds 17.5% to the price when USD is selected, becomes approximately 13.7% when we choose GBP.

Here is a link to a video of this problem:

This discrepancy is a significant concern for us and needs to be addressed before we can proceed further. Could you provide a patch or fix for this issue?

Thank you,
Gunter
