This issue only needs to be tested in one device. This issue must be tested with a BMA or custom app.  Build an app with a siteurl set in config and displayqroncredentialscreen set to true. In the site as admin, enable QR login. In the site as admin, enable login via browser in the app. Install the app in the device and open it. Check that you see a Login button and the scan QR button. Click the Login button. Check that the browser is opened (depending on your config it could ask for confirm before opening it). Check that you can authenticate fine. Logout and click to add a new site. Check that you see a Login button and the scan QR button. Only if site is Premium/BMA: now use the scan QR button and check that you can authenticate fine.
