Ignoring notifications does not work like it does on the VRC website, which leads to visual clutter.
On the website, ignoring a notification will remove it from the notification list, requiring a click through to the Messages area if you wish to view the ignored notifs.
On the mobile app, ignoring a notification just marks it as ignored but leaves it in the list, making the list cluttered. In this way, the ignore function is almost useless.
