Hello,
I am glad to answer those questions:
1.- Yes, WooCommerce Payments is compatible with WordPress multisite installations. However, each site within the multisite network will need its own separate WooCommerce Payments account and configuration (WooCommerce Payment account is linked to the site rather than the email address.). This means that you will have to manage your payment settings individually for each website in your multisite network.
2.- The WooCommerce Payments multi currencies feature is created to cover WooCommerce Payments and not other plugins, to help you show your products in multiple currencies.
WordPress is a highly popular and flexible content management system (CMS) that has fostered a large community of developers and users. As a result, there are thousands of plugins available from various third-party developers and merchants that offer a wide range of functionalities, as a result, it can be challenging to ensure compatibility among them.
If you would like to work with multi currency, you can consider the WooCommerce Multi-Currency plugin, it will help you to set up multiple currencies on your online store to provide a better shopping experience to your international customers. The top 3 functionalities of this plugin are:
1. Multiple Currencies Support: The plugin allows you to add and manage multiple currencies in your store.
2. Automatic Currency Conversion: The plugin automatically converts product prices, shipping rates, taxes, and order totals into the selected currency using up-to-date exchange rates.
3. Customer-Centric Currency Selection: The plugin lets customers select their preferred currency from a currency switcher in the store, improving their shopping experience.
I hope this provides clarity.
