Website browser issue

A website I built is showing up in Italics just in Safari.
Any idea what the problem might be?

(The dev who helped me said it’s bec. the default of this font is Italics, doesn’t make sense to me)
Font is Acumin Variable Concept


Update: in browserstack it shows italics on iphone/ipads as well.
I tested on real iPhone and it was fine.

Can anyone shed light here?

When you tested the real iPhone, was it the same version/etc as what you tested in Browserstack?
Can you post a link to the site?

I think the issue was a variable font (Acumin variable), when I switched to Acumin Pro - the issue resolved.

Still not sure why tho…
