Hi there @filsch
Thanks for your question!
`i can’t set many products to “sync and show”, they remain to “sync and hide”.
The products are published AND do not have variations.
Probably the problem occurs when i duplicated the products.
How can i solve the issue?`
Ah I see, that’s really odd!
First of all, you will need to ensure that when you duplicate products, there are no duplicated products synced to your Facebook catalog except it’s done deliberately where you adjust the info of the duplicated product as a different product (changing its title, price, images, slug etc).
Secondly, could you please do a conflict test and try again?
Before doing a conflict test, please ensure you’re running the latest version of the plugin and also please clear WooCommerce transient data here: WP Admin > WooCommerce > Status > Tools > WooCommerce transients > Click - Clear Transients (Button on right)
To do a conflict test, please complete the following:
1. Temporarily switch your theme back to the?Storefront?or?TwentyNinteen?Theme and test for the issue
2. If the issue persists, disable all plugins except for?WooCommerce and Facebook for WooCommerce.
3. Test to see if the issue has been resolved.
4. If that resolves the issue, then one-by-one you can switch back your theme and re-enable your plugins, testing in between, until you find the one causing the conflict.
Let me know how it goes!
