I am finding that RadaMan iOS in March 2025 will process a universal link if the user clicks on it Taps on it. But if you copy paste it into the browsers URL bar, it doesn’t work and the browser takes you to that URL as a webpage Instead of opening another app.

On Monterey 12.3.1 with Magic Mouse, scrolling disappears and then reappears. Doesn't seem to correspond to battery level. If the mouse disconnects and reconnects from Bluetooth, that can restore scrolling.
