Share / embed feature not showing any music on score /share window or website

My first embed code snippet worked a few days ago. They score with playback was on my site and working beautifully. It's such a great feature - for playback on my website with tempo adjust & following the music etc. BUT, I just tried with a different score (multiple scores actually) and now none of them are working, or even showing up. On my scores page after clicking share / embed, the music just doesn't show (before inserting code on my site). I can copy the link but there is no visual score preview. And after inserting the code snippet on my website, it's the same - no score / music visible. It's just not showing up anywhere. Is anyone else having this issue? Quite a tease having the first one work and now none of them.. It's such a better feature with the playback and tempo adjust than just uploading the pdf. I really hope they can work out the bug here. But I'm sure with the cloud publishing feature being so prominent they'll fix this issue soon. But I assume others may be having a similar issue and wondered if anyone has any recommendations that I could try. Thanks!
