Q3, DeoVR always latest version from Meta Store (automatic updates).
What others mentioned about a video staring but the time-stamps/positions not properly appearing in the UI: this may have started several weeks or a few months ago.
Right now, the aforementioned issue is less frequently appearing for me. Instead, I am getting much more often spinning dots still in the grid view (that is before the player UI appears) after having clicked on a video. The percentage of videos for which this happens on a specific day may vary. Not sure when this started but I think in 2025.
Yesterday, close to the end of my session, about every other click or action in DeoVR returned server time-out or error messages. This may have been a temporary and exceptional issue but is adding to the picture.
