Legacy embeds

The Legacy embed blocks were migrated over from the previous CMS and don't cause any problem, unless the page needs to be updated. In this case, the presence of the embed HTML will cause the Tate firewall to block the page from being published (or saved). Most of the pages affected are those containing YouTube embed code. Steps to fix this are listed below:

Fixing Legacy embed firewall issue

1. Copy YouTube video link from the Legacy embed (i.e. https://www.youtube.com/embed/VID_ID) and paste this in a new tab so you can grab the share link later
2. Delete the code within the Legacy embed block
3. Publish the page (you will get a 'required field' error)
4. Delete the Legacy embed block
5. Add the Embed block
6. Paste in the YT share URL (i.e. https://youtu.be/VID_ID)
7. Publish
8. Page is now ready for regular editing
