Instagram's built-in browser is affecting the look of my website

I couldn’t find any other information on this topic but as the title mentions, my website appears ever so slightly different in Instagram’s built-in browser. The site is just a simple landing page until the final one is ready so I’m hoping I can fix this now before it propagates into a bigger issue going forward.

The problem: Essentially, there is a bar underneath the name AVDA that fits the width of the letters exactly but on Instagram’s built-in browser the bar appears larger than the text.

I’m wondering if there’s something I can do to fix this, any help would be greatly appreciated!
