Screen shrinks when contact form text field is selected

Hi guys,

I’m having an issue with my contact form.

It looks good in every mode BUT when I’m on my actual phone and try to use it, as soon as I click on the text area for the cursor to appear to start writing, not only the text area and contact form’s height shrinks but every single component’s height on the page shrinks. As soon as I click out of the form, everything goes back to normal… I can’t explain this behavior, is it because I used “vh” measurement ? I don’t know why the height would change when I click and why it would affect the whole page…

Thanks so much in advance,
