Multiple users reported that the 'Double Tap for Passthrough' feature, previously toggleable in settings, is now forced on with no option to disable in v81. This change has caused issues with mixed reality games and applications, as accidental triggering of the feature occurs when touching the headset or head strap, or when bringing hands near the head. The loss of tracking and subsequent re-tracking of spatial awareness during PC VR via Steam Link or Air Link is particularly problematic, resulting in a jarring experience. Users request the reinstatement of the toggle option to allow for control over this feature.
