Vendor Notify Approved Denied not working

I want to solve this problem as soon as possible.
Please tell me the solution.

Hi there,

There might be something from your settings that could be causing this. I would recommend checking our guide to debug email issues like this – https://docs.wcvendors.com/knowledge-base/debugging-mail-issues/

Let us know how it goes afterwards. Have a nice day ahead!

Hello.

Will you test it with WooCommerce 4.7.0?

thanks
