Struggling with UE5 lighting and shadows in mobile VR (Quest 3)

Hey everyone! (I don’t kwon if it’s the right section to post) I’m learning Unreal Engine 5 and particularly how to create VR projects with it (for the Quest 3). Right now I’m using the VR template as a base to test everything and I managed to build the apk and run the app on the Quest. I have two questions : 1) when I switch to the Android preview(this happens also on the headset), the 3D models marked as movable lack contact shadows and shadows in general, Why? It is possibile to fix that? 2) I’m struggling to implement dynamic shadows. Is there an easy way to have dynamic shadows in the project? Will it have an impact on the performance? I’m a newbie, so please be kind and patient with me ahaha ! Any advice would be greatly appreciated (or also if you have a link of a YouTube video or tutorial in general that covers this topic.) Thanks in advance!
