CSS in Tiny Theme not changing after edit

I resolved my issue on Blog does not load CSS by transforming my custom theme into a plugin. I added a plugin.json file in the root folder, to ensure that micro.blog incorporated the custom CSS and other static files needed for my custom theme, like this:

{
    "version": "1.0",
    "title": "My Customization",
    "description": "This is my customization",
    "includes": [
        "/css/custom.min.css",
        "/fonts/iosevka-fixed-ss03-bold-1731a53e9517931037d93cd9b5cf656a.woff",
        "/fonts/iosevka-fixed-ss03-bold-3146aa514ee08a1ed552599d8ce1c029.woff2",
        "/fonts/iosevka-fixed-ss03-regular-5cda2e12355dd1a046c368ed4a0e31ce.woff",
        "/fonts/iosevka-fixed-ss03-regular-b7aed84b4a3d74e5afed3a3438b0dc2b.woff2",
        "/images/logo.png"
    ]    
}

Please note that all the paths listed in includes are relative paths pointing to files stored inside the static folder, so for example /images/logo.png is actually referencing /static/images/logo.png.
