I bought the app on the tunes and unfortunately the step by step mode does not work properly, I am not shown the complete procedure but only a part. HELP
It would be best for you to show precisely what you tried to do. Your post is too vague. Provide details.
for example, in the resolution of derivatives or integrals, when I click "step by step solution" the page does not scroll but only the first steps are shown and when I try to scroll the page she does not scroll.
