My apologies for the extremely delayed response.
What worked for me was ACF Code Field. In that, we can’t directly add iframes. However, adding iframes within a shortcode works. So, I’m coupling ACF Code field with Advanced iFrame Pro and it’s been working like a charm.
Here’s a working link – https://businessquant.com/intel-revenue-by-segment
Hope it helps
joenathan78, check out ACF Code Field. It’s a workaround and it’s working for me.
