Session Expired message showing for non-logged-in users (with FlyingPress cache)

Hello everyone,

I’m facing an issue with FluentCommunity on my WordPress site. On the homepage, non-logged-in visitors are seeing this message:

Session Expired
Your session has expired due to inactivity. Please refresh the page to continue.

This message should only appear for logged-in users when their session actually expires.

My setup:

• FluentCommunity (latest version)
• FlyingPress caching plugin enabled
• CDN (FlyingCDN/Cloudflare) in front of the site

Problem:
It seems the “Session Expired” banner is being cached and then shown to logged-out users as well. This creates confusion because normal visitors should never see this message.

What I tried so far:

• Clearing cache (FlyingPress + CDN) → problem comes back.
• Checked cookies → non-logged-in users don’t have wordpress_logged_in_ but still see the cached banner.
• Looked for a way to bypass cache based on cookies, but that might not be optimal.

Question:
👉 How can I ensure the “Session Expired” message only shows to logged-in users, and not cached for public visitors?

Any hooks, Bypass Cache for Cookies, filters, or recommended FlyingPress/FluentCommunity settings would be greatly appreciated.

Thanks in advance!
