Same things for me.
There is also a problem into the content field. There´s a bug when trying to digit in the visual view and impossible to write or do anything in the text area.
Is there a conflict with pag builder?
Looking forward for updates.

Installing Gutenberg plugin fixed it for me as well!
Installare Gutenberg plugin ha risolto il problema anche per me!

I have the same problem. I am also getting this error. Any update on this issue? When will the new fixed version be available? can you give us some easy solution? I don't want to use this Gutenberg plugin.

Hello, I also have the same problem! We are also using WPBakery, so activating Gutemberg is no option either for us.
When will the new WPML update be launched?

Problem still persists with WPML 4.1.1 and Yoast 9.2.
Using Yoast 9.1 corrects the issue.

@alex Drakos
I am not able to reproduce the issue with WPML 4.1.1 and the latest version of Yoast.
- Did you try clearing all the cache (server, plugin, and browser)?

If the issue is still there, may I ask you to open a new ticket?
You can do it from here:

Thank you
