Hi –
Thanks for getting in touch.
Can you try disabling any browser extensions as a first step.
Here’s a list of known compatibility issues too:

I’m not using any browser extensions.
I’ve noticed from time to time that “generating preview” hangs like this, but most times it seems to work. Maybe it’s just a timing problem? (not waiting long enough for the save to complete or something…)
I was just trying it again and thought that the preview was hanging, but didn’t close the window and eventually it did work – just took a long time, maybe 10 seconds. I wasn’t expecting it to be so long so wasn’t waiting long enough.
I believe with an earlier version it really was hanging, but not sure i’m seeing evidence of that now. Will let you know if it actually hangs any more.
