I have a World UI Canvas set up and I can interact with everything on it just fine: buttons and sliders mainly. I also have a dropdown list. When I click on it, it opens up, but if I click on the list, I can drag it up and down to see the contents, but I cannot validate a choice. Is there anything I'm missing? Or is it a bug? Using Unity 2019.4.5f1 with the latest XR and XR Interaction packages. Using OpenVR Loader but am not using the Steam VR Input System. Running on Oculus Quest.
