I’m having the same issue. I’m using a quest 2 through the standard quest browser. Usually there is a right-side menu with loads of useful settings including tilt, height, rotation, playback speed, left/right offset, and a few others. Now there is nothing other than a drop down for quality and a volume bar. I can use the control sticks for zoom, but nothing else.
I find the videos to be mostly unwatchable without the settings. If I can’t figure it out I will definitely be canceling. I’m guessing this is to push me to use the DeoVR app or something, but I am not a fan of taking away functionality to push me into using an app I don’t want.
