Course Presentation Module Error - Text cut off on Mobile Devices


I am embedding a Course Presentation Module in my website using LearnDash LMS, Wordpress 5.7.1 With Astra Theme.

On some mobile devices the text gets cut off on some slides. Definitely on my current iphone. Some users have also reported same errors.

Same content displays prefectly on Samsung Galaxy 8.

See screenshots attached.

I'm suffering from similar problems. Everything is fine when the mobile app is viewed using devtools in a browser but on an actual device the content does not seem to resize properly and vertical blue lines appear. Text is sometimes cut off. Any help would be much appreciated. Please see screenshots.

I'm using apppresser, Wordpress and h5p presentations.
