Haven’t seen this reported yet and I don’t use the block editor myself, but I’ll do some tests and follow up on this extinctdisney.
tried on my development site and can’t reproduce extinctdisney, see screenshots:
lyte block test
What’s the URL you’re adding to those YouTube blocks extinctdisney (use the code markup/ button here to make sure the video isn’t embeddd here)?
You can see it, it’s showing up as text only, right beneath the image gallery.
well, I think the problem is that httpv://www.youtube.com/watch?v=embed/mGIxttHCi3M is not a correct link? can you instead try using httpv://www.youtube.com/watch?v=mGIxttHCi3M or even simply https://www.youtube.com/watch?v=mGIxttHCi3M or in it’s simplest form https://youtu.be/mGIxttHCi3M?
That isn’t the issue. That is what is appearing on the page but the actual link to the YouTube video is what is placed in the WordPress YouTube Embed Block. Again, if I turn off your plugin, the video is embedded fine (but without my settings to make the player smaller etc.). I should mention, I see the video/block just fine on the post edit page.
Weird extinctdisney, as all works for my tests the only thing I can think of now is a conflict with something else (plugin/ theme)? If you’re up for it disable/ re-enable plugins one at a time and if needed briefly switch themes to see if you find a culprit?
It appears if I remove the blocks that existed before 5.6, update the post, and then add a block again, it’s working. I have no idea why but considered this resolved.
Good you found the workaround, but frustrating indeed as I don’t have an idea what was happening there either extinctdisney :-/
