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 hope this changes, it’s what keeps me on AdGuard :-/
