Explanation

Fix #3472

Now @rt4914 PTAL @prayutsu

These are the screenshots of the activity

In the last screenshot there is a scroll view so the whole page is scrollable

@yash10019coder From the PR description, it is not clear if the screenshots attached were taken before the changes or they have been taken after the changes, to compare we'll need both screenshots.
