iOS native App no Uploads an Avatars visible


We are unable to download and view uploaded files via the iOS native App (V 3.5.1).

For Instance: An uploaded picture only appears as a white space and no interaction is possible. Like the uploaded pictures Avatars appearing in the same way - only as a blank space.

On the same iOS-Device in the RocketChat-Experimental App everything is fine. On Android there are no Problems too. Therefore i think there is no wrong serverconfiguration.

We like to use the iOS native App. Could you please help us to get the iOS-Native App working?
