After either the 0.17.9.0 or 0.17.9.1 update, the blocker volume is blocking the ability to hold Q and access the media panel (the one used for adding media, or voting to skip).
Note: blocker is only set to “Block Players”
Before the update, blocker didn’t block this function. I know for a fact because I used blockers in the IMAX areas to keep people from falling into the large gap, and people could still skip vote through the blocking volume.
