Just tried it on a video about WHO and Bruce Alyward. It's still up after 6 minutes. Either we're inundating their censor bot, it's been shadowbanned, or Google has stopped under the flak. I'll keep checking later.
Try looking at your comment in an Incognito window and sort by new. You'll still see your own comment if you're logged in, but you won't see it otherwise. I just tried this.
