YouTube videos not embeded

@Francisco, I experimented it before WP5.6

Hi Tom,
I'm back with this problem.

"Can you try deleting the GeneratePress Theme.
And then re-installing the theme"
Done... and same issue.

I don't know what to do. I noticed a similar behavior with an Instagram URL in another page somewhere in my site.

Hello Francisco
Have you manage to solve the issue?

Yes, no problem.

Thx.

Could I ask what you have done to solve it?

At first I installed a plugin to embed youtube, but since the last update of wordpress I have deactivated it and everything works correctly.

Ok, thank you. I gonna try that and will come back in a couple of hour with the outcome.
Thanks

Your counter solution works for me Francisco.
I have installed "WP YouTube Lyte". Now all the YouTube videos are correctly displayed.
If a deactivate it, some are not displayed with GP while there are with the official theme provided with Wordpress.
I have tried to reinstall WP w/o success.

I keep WP YouTube Lyte activated for now...
