I have a problem I just can´t solve. I display a Google Sheet inside an HTML-component using the messaging interface. In preview mode, all is well, but in the published version, the sheet is empty (but the below string is passed on OK)
Google gives you something like
<iframe src="https://docs.google.com/spreadsheets/d/e/2PACX-...etc_/pubhtml?gid=1932313782&single=true&widget=false&headers=false&chrome=false" width="750" height="1500" style="border:0px"></iframe>
So it can´t be the https-https documented difference in behaviour between published/preview mode.
Anyone got any idea?
