Hi @topps,
I’ve tried replicating the issue at my end. But things are working fine. I do not see any message related to incompatibility.
I have WordPress 6.7.1, WooCommerce 9.5.1 and Quotes for WooCommerce 2.7 (https://app.screencast.com/niYqdecDvqAmn)
As you can see the Ask for Quote payment method is available in the Blocks based checkout page. It’s strange that you are receiving this warning. I know of many plugin users who are using the plugin with blocks based Checkout without any warnings or issues.
Can you kindly try to deactivate and activate the plugin once?
I suggest you try to use the blocks based Checkout page in spite of the warning and let me know if you can see the ‘Ask for Quote’ payment method at Checkout when the cart contains quoted products.
Please let me know.
Thanks,
Pinal
