Getterms.io provide privacy and terms of use policies which can be embedded in websites via Javascript, and the Brave browser (on mobile and desktop) blocks them.
Getterms.io also provide cookie banners, so I can understand why you may have put a blanket ban on them, but showing a privacy notice is something I assume you’d like to encourage, so please could you consider not blocking their embed scripts.
Their scripts require access to https://app.getterms.io/dist/js/embed.js.
