Another issue I've come across using an Index w/ DeoVR: when playing downloaded scenes, there is roughly a 1/3 chance the scene will not load properly. It will only load a black screen with the menu bar, but the video will not start. If you back out from the video to the file folder and relaunch the same video it will eventually play, but sometimes that can take as few as 2-3 attempts and other times nearly a dozen attempts.
Was not something that came up at all until immediately after the new update.
Sorry if this was already mentioned somewhere else, hard to keep track.
