NO Header Logo SVG / Mobile

It’s about a simple OceanWP 1.5.21/Elementor 2.1.6 OnePager (WP 4.9.7).
Had a JPEG logo and everything was fine but quality/size.
So I uploaded an SVG version of it and it worked even without your how-to https://docs.oceanwp.org/article/357-how-to-add-an-svg-logo and the SVG plugin.

But when the theme reaches its mobile breakpoint of max-width: 767px the logo disappears. All caching and optimizations deactivated, browser cache cleared, tested and reproduced on FireFox and Chrome. And that also WITH your how-to applied (SVG plugin and code in the custom CSS section).

Also tried to set a retina image for the logo (Design/Header/Logo). Used the same SVG and a renamed, additionally uploaded SVG, and another JPEG. None of them will be shown on the Win10 Desktop but at least the JPEG appears now on the smartphone browser.

When I enter Design/Header/Logo again after I saved a retina SVG there, the retina option always says ‘no image selected’ and is empty again.

For me this looks like a bug within the theme related to some media query and SVG.

I’d also like to send you a link to the website but I really don’t like posting links of development installs all around the web. Sadly you only give internal ticket support for paid customers – even for the free theme itself.

Can you help me out here?
Thank you in advance and best regards
