The Issuu embed block is not responsive on smaller screens. The embedded JS that comes from Issuu adds an inline width: 640px and height: 461px to the <iframe> container block regardless of the screen size. An easy solution is to add some CSS: .issuu-isrendered { max-width: 100%; }

Additional context
Thanks for opening this issue.
Unfortunately the styles and the content of the embeds is not controlled by WordPress, this issue is better raised directly to the oembed provider (issuu here).
Although we're not able to control the style and content, we can definitely make the container responsive, which will also make the iFrame in it responsive:
.embed-issuu {
position: relative;
max-width: 100%;
height: 0;
overflow: hidden;
padding-bottom: 75%;
}
.embed-issuu .issuuembed {
position: absolute;
left: 0;
top: 0;
width: 100% !important;
height: 100% !important;
}

Hi
Same here.
WP 5.3.2
The embed has a style in the <div data-url="url_from-issuu" style="width:1200px;height:848px" class="issuuembed issuu-isrendered">
Change the style to style="width:100%;height:848px"makes it responsive
EDIT: Now issuu embed is only for payd users. See https://help.issuu.com/hc/en-us/articles/211809598-Embedding-Your-Own-Publication
"NOTE: The Embed feature is not available on our Basic plan. It is available only on our paid plans - Starter, Premium and Optimum. Users on Basic plan will not have the ability to create embeds路
