Error rendering when using @customgroup in mobile app

[LouisSung]

Hello,
I'm not sure if this issue is related to the plugin itself or the mobile app _(:3

This is how a @customgroup* example renders in web interface, which works as expected

However, the same message renders wrong in mobile apps (both iOS and Android versions), whereas the normal link such as [herf](http://example.com) still works correctly

ps. I also tried the example one, i.e., Pattern: @customgroup* and Template: [@customgroup]( \\* @user1 @user2 \\* ).
However, it failed as the complex pattern & template as shown above and therefore the issue may not be caused by using error template

---

Here are the questions:

1. Is the @customgroup rendering as an expanded link in mobile apps on purpose? or it is a bug?
2. If this is a bug, should it be reported here or @mattermost/mattermost-mobile

Thank you : )

Is there any further update? 👀
Still wrong using autolink:1.2.0, mattermost-enterprise:5.26.2, and ios-app:1.34.1
