Hello, we recently wondered why images are not shown in our customer mails and stumbled about a missing scheme for images. Instead of

https://host.yves/default/img/logo.svg

Something like

//host.yves/default/img/logo.svg

was generated. We think this is a faulty implementation in the YvesUrlFunctionProvider, since it does not add any scheme based on the is_ssl_enabled config for example. But then i saw also the file mail_layout.html.twig which also has a static link NOT including any scheme

<//www.de.project.local/assets/default/img/logo.svg>

I am confused now … my assumption is, that this is the reason why it will not work in any mail program even if mailhog can resolve it. Did somebody faced this issue too? Best
