Our ward had a trans woman, so the policy was when they wanted to go to the washroom, they just needed to be alone and not have anyone else in there-mind you the assumption being that trans people are pedophiles and molesters. Given though that you can't trust Bishoprics, Stake Presidencies, Mission Presidencies basically anyone interviewing anyone is assumed to be a pervert and would do something in the office. Everyone is suspected now
ETA-I do know that the Church is cracking down on the video training for people working with children, basically if you don't do it you can get released from your calling.
