App Twin functionality, which requires some kind of private container space, is inherently not supported on Android-Enterprise (AE) devices.  To officially confirm this, the best you should do is probably to ask Huawei support team directly.

I don't know if you have tried using this "App Twin" function successfully on device with MobiControl Android+ device agent (or non-AE agent of other EMM solution).  Even if it works,  I would not recommend using it for my governmental customers due to security reasons, except only for implementation based on Samsung KNOX platforms which is known to be a hardware- plus kernel- level container implementation.  The implementations on other brands (Huawei, Xiaomi, etc.) are likely to be user-level container.

What do you mean by "cloning an app"?   You can clone an uninstalled Android app in .apk format to another .apk file of a different filename, but cannot clone an installed app.   If you refer to an installed app, do you actually mean creating a shortcut?

Thanks for answering.

I refer to the "App Twin" function.

This option of terminals enrolled as managed devices is not working.

Thank you.

You meant "App Twin" on Huawei EMUI? Or some other brand?

Are you using Android-Plus or Android-Enterprise device agent on such device?

In this case is Huawei EMUI with android enterprise
