I've my module files as following
app/code/Vendor/GeoIp/view/frontend/layout/default.xml
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<head>
<css src="Vendor_GeoIp::css/popup.css" />
</head>
</page>
My CSS file at following path
app/code/Vendor/GeoIp/view/frontend/web/css/popup.css
Other code of module is working fine, I cleared cache,s:upgrade,s:s:d many times but it isn't working.
I can't find any mistake in above code. What is wrong?
