* Convert NotificationsFragment to use view binding * Use requireContext() in places a context is required Removes a nullness warning. * Simplify code by using .sublist() and .contains() Removes a lint warning. * Add @NonNull annotations to onViewTag and onViewAccount * Use consistent comment styles
