Flexible Product Fields Pro (by wpdesk.net)

What "compatible" means here

No adaptation code is needed: prices from this plugin already pass through the FOX conversion, so they follow the currency the visitor selected. Nothing to install, nothing to paste into functions.php.

Two things are still worth checking on your own shop before you rely on it:

• The amounts on the checkout page, not only in the catalogue. Conversion on a product listing and conversion at checkout are separate paths, and this is where mismatches show up first.
• Fixed per-currency prices, if you use them. A plugin that calculates its own amounts works from the base price, and a fixed price you set by hand is not that. Where the two disagree, the woocs_fixed_raw_woocommerce_price filter is the attachment point.

If something does not add up, the fastest route is not guesswork: send the case through FOX LABS and we investigate it and publish the adaptation free of charge.
