Hello!
Thank you for being interested in our plugin! PWAcommerce does not yet support external products, they will be implemented in the next update.
However, the products should still be visible in the app. Please check the following:
– Can you access “yourdomain.com/wp-json”?
– Do you have “pretty permalinks” enabled?
– Have you enabled the WooCommerce REST API?
– Have you generated a WooCommerce API key and entered the ‘consumer_key” and “consumer_secret” into the PWAcommerce settings menu?
