Adjust Cross-sell pop up Button and text

Are you able to help me adjust the text size of the button on cross-sell pop-up? It’s too big that it got cut off. See attached.

Also on mobile devices – Can you center the alignment of the title?

Lastly, with the discount bar switched on, can you move the cross-sell pop-up slightly higher so that it does not get cut off? this happens on the website view.

Thanks in advance.
