LineageOS is currently installed on 1.5 million Android devices

I can't confirm if all features are working, but possibly. My case is that I have LineageOS on my phone and my son has an Amazon tablet that I've used Fire Toolbox on to install Google Playstore and services. I'm able to approve/deny apps for him to install (I get the notification on Family Link on my phone), but some things aren't working because I'm having trouble with Play services on the tablet.
