Problems with one click unsubscribe link on Desktop mail clients

[Selliers]

I have run into a strange challenge it seems. In my email surface configurations it seems to be right set up, since the link shows up in the inbox on mobile clients. But for some reasons nothing happens when the email is read on a Desktop client. Why should it work fine for mobile and not on Desktop? I cant get my head around what the problem might be. The code used is same just viewed in different clients. Does anyone have any clue ??

@Selliers these all depend on the email clients. There's no workaround to address this issue at the AJO side. Do you see this behavior in all the desktop clients?

I am not sure that this accurate since you need to create the link to a one click opt out inside the email template, so this has something to do with AJO also. For some reason the link that is created works for mobile (the unsubscribe to list) is present on mobile screens, but not on Desktop (all desktops). It actually works different it the code is red from a mobile client - so i suspect that the code that is generated from AJO is not compliant on Desktop clients.

As Sathees mentioned, the code has nothing to do with AJO. This is an industry standard code for all emails

{
  "List-Unsubscribe-Post": "List-Unsubscribe=One-Click",
  "List-Unsubscribe": "<mailto:unsubscribeexampexample@example.com>, <https://www.unsubscribe.example.com/>"
}

Support for list-unsubscribe varies across email clients. While some email clients honor mailto or URL-based list-unsubscribe headers (or both), others don’t support list-unsubscribe at all. The following email clients support list-unsubscribe:
