Connect App - constant notification blue bubble without actually new notifcations present

somebody else noticed as well that since a couple of days the Android Connect App (v5.16.2) constantly shows a notifficiton reminder (blue bubble) without actually new notifications present?

I felt strange why I'm getting all of a sudden so many notifcation (thought they would be new) so I deleted all received&past notifications and voila the blue bubble is still reminding me

for having a new notification without actually being true. Anybody else noticed this issue?
