iOS maps in dlc won't show up

Hi,

I’ve created an iOS app which is downloading dlc but the maps included in the dlc won’t show up in my app.
My blueprint setup is very similar to:

https://docs.unrealengine.com/en-us/Engine/Blueprints/UserGuide/PatchingNodes

When checking the file system on my test device there is a pak file located in a folder called PersistentDownloadDir.
Also the MountNode returns true when called.
At the MountNode i’ve left Pak Order at 1 and tried several Mount Points (Content/, empty) but no success.

After the patching process I try to get all installed maps with a setup similar to this one:

Anyone got DLC Patching Nodes working on iOS device?

Best regards

Anyone can help me out here?
Mount Blueprint Node seems to be broken for iOS build …
