Issues embedding AppSheet in a Google Site

[pswanson22]

I’m having some issues embedding my AppSheet in a Google Site. I found this help article (https://support.google.com/appsheet/answer/10104491?hl=en) but it is not matching my experience.

It says that app embedding can be turned on under Security > Options > Allow app embedding. However, when I go to Security > Options I don’t see any option for app embedding.

I tried to embed my app anyway using this code: Embed from the Web (by URL, Whole page): https://www.appsheet.com/start/1e141fe7-8dab-406a-8a3f-a4b311c4df28

When I do so I see this:

Does anyone know how to do this?

Cheers,

Paul

Here is the Security Option page of one of my Apps.

What do you see on yours?
