Comment Bubble not Responsive

We like large comment bubbles but:
Comment Bubble behaving weirdly on mobile devices (small screens)
It overlaps text (post title) and becomes unreadable.
Please check the link I provided on the mobile device for a clear picture.
We tested it on an Android device and “Customize” mobile view option – same weird result.
We use Customizr ProVersion: 2.0.23 and cannot update it, as our key expired.
Is there any code to fix this issue?
