The best part about push notifications is that it works even if I have turned off my phone or computer for some reason! It's really simple to set up; just choose what platforms/tools want updates from me (Facebook Messenger / Slack) then add them all into one list in this little window here under "Push Notifications Settings." From there everything else flows naturally -- no need install anything extra like other services require-- simply turn things ON &" OFF" with ease now without having any problems later downthe road!!
