LineageOS - is it possible to install and run apps without using Gapps or MicroG?
Many people are going Google-free and gapps-free now.
Do it like this:
Install F-Droid store, then install Aurora store from F-Droid.
Aurora store is to install apps from Google Play store.
Most Play store apps will run fine...  some won't.  For those, look for alternatives.
