I came from FP2 LineageOS 16.0 for microG. Since 3 months with /e/OS with MicroG.
Status: Rooted with Magisk
Appstore: F-Droid & Aurorastore
All apps I already used with LineageOS 16.0 for MicroG are still running without problems.
only one minus point: Battery drains 50 % empty within 6 hours without doing anything except auto sync
FP2 still my only daily driver
