Currency Conversion Issue with PayPal Option

I have installed the CURCY – WooCommerce Multi Currency plugin on my WebShop. I set the main currency as BAM, but since PayPal does not support BAM, I configured it to use EUR for transactions. I noticed that when a customer selects the PayPal payment option and immediately clicks the payment button, the system does not automatically convert to EUR; instead, it shows the error “CURRENCY_NOT_SUPPORTED Currency code is not currently supported.” However, if the customer first clicks the PayPal option and then, for example, changes the shipping choice or enters some details in the form, it automatically switches from BAM to EUR.

Is there a way to immediately convert the currency to EUR when selecting the PayPal option without the need for additional interactions or changes?

Thank you in advance for your assistance.
