we have a list with a rich text field and used Nintex Forms to designed it.
Now we tried to embed media (e.g. YouTube videos), but unfortunately it seems the specific ribbon buttons ("Video and Audio" and "Embed Code") become disabled by SharePoint in a Nintex Form.
I made a test list and can confirm that it works in the SharePoint 2013 default form but doesn't work in the Nintex Form.
This behavior breaks a core feature of SharePoint 2013.
Do you have any ideas, how to solve this issue?
