CSP Issue in WordPress with No Unsafe Inline Plugin & .htaccess

Hello everyone, I’m experiencing an issue with Content Security Policy (CSP) in WordPress while using the No Unsafe Inline plugin.Issue:

• When I enable CSP Protection in the plugin, the only policy that appears is upgrade-insecure-requests ?
• However, when using Report-Only mode, all CSP rules appear correctly ?
• I also tried applying CSP rules in .htaccess, but when CSP Protection is active, they do not show up

My CSP configuration in .htaccess:

Header set Content-Security-Policy "default-src 'self' https://*.google.com https://*.googleapis.com https://*.gstatic.com https://secure.gravatar.com https://cdn.amcharts.com; script-src 'self' https://*.google.com https://*.googleapis.com https://*.gstatic.com https://cdn.amcharts.com; style-src 'self' https://*.google.com https://*.googleapis.com https://*.gstatic.com; img-src 'self' data: https://*.google.com https://*.googleapis.com https://*.gstatic.com https://secure.gravatar.com; font-src 'self' https://*.gstatic.com data:; connect-src 'self' https://*.google.com https://*.googleapis.com https://*.gstatic.com; object-src 'none'; frame-ancestors 'self'; frame-src 'self' https://*.google.com https://*.googleapis.com https://*.gstatic.com maps.google.com; worker-src 'self' blob:; form-action 'self';"

What I’ve tried:

? Checked Network → Headers in DevTools → CSP rules are visible in Report-Only mode, but when CSP Protection is enabled, only upgrade-insecure-requests appears.
? Cleared WordPress & browser cache.
? Disabled caching plugins like LiteSpeed & WP Rocket.
? Removed CSP rules from .htaccess to test whether the plugin is applying them correctly.

Questions:

1?? Why do all CSP rules appear in Report-Only mode, but when CSP Protection is enabled, only upgrade-insecure-requests is applied?
2?? Could there be a conflict between the CSP settings in .htaccess and the No Unsafe Inline plugin?
3?? How can I ensure that CSP rules from the plugin are being properly applied without being overridden?

Any insights would be greatly appreciated. Thank you.
