Text and text boxes not rendering correctly on mobile

I published a web story today that looked perfect on the preview. However, when I went to view the same story on mobile to make sure that everything was appearing properly, the text and background text boxes are not correct. It looks like the text box is not covering the entire text and the text is not structured how I had it.

After checking this web story, I went to view all of my web stories on mobile and it looks like this issue is across the board. It also happens when using both Google Chrome mobile and Safari mobile. I have also noticed this issue when using other mobile devices. Please note that I do not notice it when viewing my web stories on desktop–only on mobile, and this is the first time I’ve seen this issue (I published a web story as recently as two weeks ago with no problems). Both my WordPress and web stories plug in are up to date.
