Ring App for OSX 2.4.0 Bug

It appears that there is a small bur with Ring for OSX v. 2.4.0 (745). Even after closing the app, I still get movment notifications (i.e. the sound associated with a motion alert). After closing the Ring app, whenever there is a motion alert, the sound gets played with a small pop-up window. There is no video (as expectedd since the app is supposed to be closed). I have looked in Activity Monitor to see if I could find a process related to Ring to explain this behavior, but so far I have not been able to find it. This is not a big deal, but it is annoying to keep hearing the audio amotion alerts after the app is closed.
