Logo not showing on mobile

Very strange problem, which I’ve never had before with Astra.

Whether the logo image is in the primary or above header, I can’t see it on mobile view even in the responsive view in the customizer as well as on my phone. On my friend’s phone it does show up but really small.

I used the same logo files on a different Astra site of mine and there’s no problem – it shows up on all devices.

Any ideas? Any settings controlling the logo I may not know about?
