Installation is the first step, then you must enable it.

If you go to safari settings and enable it there, then you are using it.

And then am I using it if I'm loading the extension by interacting with it? Because simply enabling it will not give it access to the webpage.

Bizarrely when I do that it tells me “uBO Lite is not supported by this version of Safari”.

On an iPhone 13 with the latest version of iOS.

I’m very new to the Apple ecosystem so it could well be that it’s meant to work on a laptop/desktop rather than the mobile version.

I could of course be wrong: does anybody know better? Or is it a case of me being frazzled after work?

EDIT: some users have suggested upgrading to iOS 18.6 solves this problem. Doing it as we speak!
