Is there a community that you’ve instead joined?

One problem is that Restricted Mode has been turned on for some users, some videos are not shown to viewers when it's turned on, and videos that are labeled as restricted are done so automatically by a faulty AI system.

You can see if restricted mode is turned on for you. Once on youtube.com, click your profile photo, and in the menu the pops down, look and see if "Restricted Mode:" is set to "On" or, "Off". Some people have found that by default it's been put to "On", even though they have not set it.

If you're not logged in, Restricted Mode is calculated by a bizarre set of rules like your not-logged-in watching history that Google totally doesn't keep track off (ie: you watch a lot of Blues Clues, you're probably a child).

In the risk of not picking up your hyperbole, I did think the windshields block UV and thus you cannot get sunburned through them.

It's a map, and a time machine!

More like technology evolves during global wars.

Fixed that for you. Rev up those stealth fighters!
