Cisco Secure Client and Captive Portal detection

[MlatParl]

Hello everyone,
Since the implementation of Cisco Secure Client, when my computers are behind my MX, the application tells me that the network is not trusted (but does not block access).
I have to disable the detection of the Captive portal so that the network finally switches to trusted.
The problem is that with this last option enabled, it is no longer possible to connect to public wifi hotspots.
Is it a bug in the application that the network is displayed as untrusted but not blocked?
I searched in the Cisco document, in the forums and I can't find the solution.
And the Meraki support always answers me wrong....
Do you have any idea?
Thanks for your help.

You might want to look into configuring Trusted Network Detection.

Thanks PhilipDAth but I have already read this article.
In fact, the problem does not come from Trusted Network Detection but from the detection of the captive portal.
Behind my MX, Cisco Secure Connect detects a captive portal that does not exist.
But, when I disable the detection of the captive portal, the network is trusted.
I have the same problem as this person https://community.meraki.com/t5/Security-SD-WAN/AnyConnect-Captive-Portal/m-p/222075#M49822
Except that if I remove the detection of the captive portal, users can no longer connect in hotels or airports.

My problem is there....
