Thank you for your feedback.
How do you watch the videos stored on your Windows 10 PC, via SMB, DLNA or AirScreen? Have you encountered such issue before the update?
It would be very helpful if you can follow the steps below to recreate this problem and send us the log file.
In addition, we'd like to invite you to join our beta channel as some bugs may have already been patched there. If you are interested, please share with us a screenshot of SKYBOX in your library and your Oculus registered email at firstname.lastname@example.org so we could verify your status and send you the invitation.
We are sorry for the issues with Quest v1.0.5 and we are working on a fix right now.
