CTA and rich text formatting
For lead generation - the most important block is a CTA and we have nothing that we can even remotely format to look like this. The styling in Rich text doesn't work - if you add an image and align it left or right, then add a heading and body, it can work, depending on the device, but the text will scroll and the spacing is very finicky.
Also, many of the blocks don't work right across all platforms. For instance, if you add a title to a rich text field and then view it in mobile, it is actually smaller than the paragraph! Looks terrible. Add a headline to the body and use h2 formatting - it shows up right. This does not happen in other views - desktop and tablet are ok. Only mobile is messed up, but looking good in mobile is integral. If only one view can look good - it has to be mobile.
