Hi
I see now there is Inline (Iframe) and Inline (Flex)
What’s the difference between these two?
They look the same superficially, and behave much the same.
Inline (Flex) is what’s called a “script” embed, whereas the Iframe one is an Iframe embed. Iframe embeds work in some places that script embeds work in, and visa versa. Script embeds might be a bit smoother to load all things being equal. It’s not something to worry too much about.
