Using an application object breaks the automatic redirection to the captive portal

[osef]

Hello,

I'm facing an issue with the firewall's captive portal

This is my rules

Everything works : unauthenticated users are automatically redirected to the captive portal when they try to surf on the Internet

But if I had a rule like this : 

Webex / Teams / Zoom are working fine but the automatic redirection to the captive portal stop working and the user's packets are dropped by the rule 69.141...
