iFrame Not Resizing Smaller for Mobile Screens

What’s the URL of your site and what content there is in an iframe?

Yes… that would help, I meant to link it in above :/

I think the table within the iframe ha some sort of minimal width.

If that is the case, then that’s fine, but I should still be able to scroll across on the phone? The scroll works when I minimise the windows browsers to the point it clips like the mobile, but scrolling does not work on the mobile

You need to talk to whoever provides the stuff that goes inside the iframe. What’s in the iframe is not part of WordPress.

Got it sorted in the end, the fix was to include the iFrame in a div:

<div style="overflow: auto!important; -webkit-overflow-scrolling: touch!important;">
   <iframe src="https://data.oddsmatching.com/Default.aspx" style="width: 100%; height: 1400px; display: block; overflow: scroll; -webkit-overflow-scrolling: touch;" ></iframe>
</div>
