uBOL bug report: https://github.com/uBlockOrigin/uBOL-home/issues/438 , from discussion https://github.com/uBlockOrigin/uBOL-home/discussions/408#di...

    uBOL doesn't work in apps, it works only in Safari, it's a pure browser extension, the "app" part of uBOL is an Apple requirement just for the sake of installing the extension.

    Copied from #408:

    uBOL will stay a webextensions-based browser extension, I do not plan to go further than this, I do not have the time and motivation to take on more work than I already do.
    What people may ask though is that Apple maybe supports webextensions in WebApp, if that is possible at all.

I have been happy with my workaround for this issue which is using uBOL along side the AdGuard content blocker extensions (main AdGuard web extension disabled).
