The gate for the Castle Volkihar won't open at all. I always need to go in by using the wooden plate and shout. I went outside of the castle before I got the quest and apparently that causes the bug when I can't get in during the quest. But after the quest and using the wooden plate thing once the gate should be and stay open. I am doing the vampire path and I have become the Vampire Lord etc but entering in is still not working. Even the wooden plate thing fails first for like ten times before I can get in. I am playing with Switch, does that have something to do with that bug? Because my friend who is playing with Xbox doesn't have this issue and on Xbox you can also go through the gate with the plate on your first try. I tried to google this also but didn't find any discussion about this issue.
