Hi Natdecap,
Can you explain more, like the iOS version you are using and the iPhone model. Whether the app you are using to watch VR Videos is created using Unity and Google VR SDK.
As per my research, Unity and Google are no longer officially supporting Cardboard VR. And support for the same is removed in iOS 14.
Please let me know if you have any information on how we can make it work.
Thanks!
