The show/hide preview is not available on mobile. You can skip that step when posting from a phone.
Yup; since a mobile browser doesn’t have the preview option, you just don’t need to worry about it.
FYI …
The mobile browser UI does have a preview mode. Which, if you activate it while you’ve got a YouTube url all ready to go, will trigger the bug.
In the screenshot that @Fear_Itself posted 3 posts up, the icon at lower right that looks like a display screen on a desk stand is the preview button. Tap that and you’ll be looking at a preview. And if you have already added an embedded vid url, you’ll trip the bug. Oops.
While you’re in preview mode, that lower right icon changes to a pencil. Tap that to get back to input / edit mode and re-enable the onscreen keyboard.
As an aside, anyone asking for Discourse help needs to include whether they’re on a phone or a big screen. Details matter. Some of us never post on a phone and some of us always post on a phone. So it’s easy to forget that your “obvious” context is not what everyone else is doing or seeing.
True. I forgot about that. It needs to be initiated manually and isn’t automatic like a computer browser’s preview pane so I didn’t even consider that.
I also tested WYSIWYG mode to see if it tries to make a video preview and it doesn’t, it still just has a link, so it’s only the preview mode that is a risk on mobile.
I’m getting a different YouTube bug. When I click on a YouTube video is asked me “Sign in to confirm you are not a bot” but the sign in link does not work. I’m actually signed in to YouTube on another tab. All I can do is to click the YouTube logo. This takes me to the YT homepage (not the video). There is just no way I can watch YouTube videos now.
Still all works for me … ?
There is one way you could see the video....
Reply to the post containing the video.
Select “quote whole post” from the options (+) menu
Find the YouTube video address.
Highlight it
Right click and select “GoTo Https://Youtube etc”
Hmm, I’ve never seen that behavior from YouTube, ever. Not in any context. Very strange.
Fixed it. Turns out the extension Privacy Badger was blocking YT cookies!
Thank you for that, good info!
