Scroll is currently supported on these browsers: Chrome, Firefox, Edge, and Safari (in conjunction with our content blocker app). Scroll also works in the in-app browser in lots of apps, such as Twitter.
Scroll does not currently work in Brave given the privacy settings it currently offers.
If Scroll is not working, make sure you do not have an ad blocker that is interfering with it. You may also have privacy settings that keep Scroll from working, or check any troublesome URL for typical issues on our Debug page.
