Hello @KarenD72813 ,
The only significant change recently to emails has been the inclusion of an event block, for those accounts with access to the newer events beta. Can you provide any further elaboration on what you feel "has changed with the formatting?"

Can you provide any further elaboration on your issue with the YouTube links? I'm not having any issues adding regular YouTube links to my email at the moment, with any of the videos I test with. So if you can provide exact examples of the links you're trying to add, screencaps of the issue, or a detailed description of the behavior, it can help the troubleshooting process. Regarding YouTube Shorts specifically, it was temporarily available in accordance with development from the system used to pull video info for video blocks, but it's something our devs are still ironing out with the embed system used for that block.
At the end of the day, if a video you're trying to insert, including a YT short, isn't not compatible with the video block, then I'd advise using the image link alternative that functionally looks and acts the same as a video block.
Another workaround when it comes to adding a Shorts link to your video block is to replace the shorts/ part with watch?v= . For example https://youtube.com/shorts/J-mrNqVPEWM would instead be inserted as https://youtube.com/watch?v=J-mrNqVPEWM . This effectively forces the video into the normal YouTube video display on their site, rather than their newer made Shorts display, and works with the embed.ly functionality of the video block better. I was able to do this in my account with every shorts link I entered.
