This issue should be tested only in 1 device. Install the plugin attached to this issue in a Moodle site, in the local folder. In the app, login in that site and open a course. Check that you see an option "My awesome plugin" at the top. Open that option. Check you see a list of "args" and 3 buttons. Check the list of args doesn't contain any param named "first" or "second". Click the button "No otherdata added". Check that the new page doesn't contain any param named "first" or "second" either. Now click the button "All otherdata added". Check that the new page contains a param named "first" and another called "second". Now click the button "Only first value". Check that the new page contains a param named "first" but not the one called "second".
