[My maturity rating in my preferences doesn't reflect in my search.]

My maturity rating in my perferences is set correctly to include Adult content, but my search won't allow Adult content. Is there something else I'm supposed to change? 

[My maturity rating is set to adult in my preferences but I can't access anything rated adult.]

My account's been adult since I started it. I took a hiatus for real life and now that I'm back, I can't search for adult or anything, but my preferences say Adult. What happened?
