Hi @davidclare 

Have you tried altering the height and width using pixels? I’d suggest trying that and double-checking our guide for setting this up. 

If the altering the pixels doesn’t help, please start up a chat with our support team or send them an email at support@slido.com. Any screenshots you can share with them will be a huge help, too.

When I try and embed the link I get an error message

Hello @davidclare 

thank you for the screenshot. The url seems to be fine from what I have checked. However the error message is not ours so it is difficult to investigate what could be the problem. Could you try pasting some other iframe link for example for youtube if it would paste any video with the iframe url? 

I am just trying to understand if the issue is only with Slido or it is the CrowdComms. 

Kindly
