Number of clicks required to clear out notifications seems avoidable & system response could be improved. Example... to clear out 80 document notifications. Must click Show More several times (wait) then scroll to very top to select Mark All As Seen (motion), confirm (no spinning wheel indicating click was recognized), wait more than few seconds for clearing, then must refresh page to update notification count and show non-document-related notifications that still remain (motion)
