Using embeds such as instagram and twitter in rich text such as on this page below appear cut off part way when publishing them. I was able to wrangle the twitter one by editing its custom size, to try and make it full size, but it now appears with large gaps beneath it in the backend, and a small gap beneath in the frontend that I can’t address, and thus seems a bit unstable. Trying to do the same with instagram embeds had no such luck as it’d vastly increase the size of the instagram post in the process, from what you can see on the page into one that fills out its available space. So I’ve had to stick with that one being cut off.
Thanks a lot for any help!
