Please can you clarify your official help page here
as I'm sure it's the problem I'm experiencing! I've embedded the map into a blogger page, but it shows a blank. If I click on the 'full screen' this is fine. I've tried defining the size of the frame by tinkering with the html. But this hasn't worked either.
Please can you clarify what to do as your answer doesn't really explain (at least, clear enough for a non-tech like myself). Thank you :)
Let me know if this article helps. Not all web platforms simply allow iFrames and that is the code we are providing you. It looks like you might have to do a little research regarding iframes and the platform you are using. Here is something I found and hope it helps.
