Hmm, that has not been my experience with Lineage at all. Over the last couple of years I have flashed several devices with Lineage and it has always worked almost seamlessly. Maybe the difference is that these devices have mostly just been popular Nexus/Pixel with official builds. (Except for my Nexus 7 where I flashed an unofficial build since Lineage no longer official supports the greatest tablet ever made shakes fist angrily)
