TORONTO - YouTube is apologizing to its LGBTQ users for an ongoing technical issue that filters out some gay and trans-themed videos for some users.

At issue is YouTube's "restricted" designation, which lets parents, schools and libraries filter content that may be considered inappropriate for users under 18.

Johanna Wright, YouTube vice president of product management, says the "feature isn't working the way it should" and pledged to "fix it."

Recently, YouTubers began noticing some videos with LGBTQ themes weren't showing up under the restricted settings, despite having no obvious age-sensitive content.

Toronto video producer Michael Rizzi saw his "7 Things I Love About My Boyfriend" video disappear in restricted mode, while transgender creator Stef Sanjati saw her make-up tutorials filtered out.

YouTube previously acknowledged that some health and politics videos may also be caught in the filter.
