I have created a theme in vendor directory. I want to override layout xml files in my theme directory. I have theme-frontend-themename. I have a folder in this directory named Magento_Theme. I want to override default.xml file. My custom theme ” theme-frontend-themename” is not overriding layout files of theme folder.
My path /vendor/vendorname/theme-frontend-themename/Magento_Theme/layout/default.xml but default.xml is not overriding
thanks
