If it's the official 18.1, yes:
If you're upgrading from official lineage 18.1 or just updating from my unofficial 19.1, do the following:
1. go into recovery mode.
2. sideload the official 19.1 rom zip.
3. if you have gapps installed, or any other zips (like magisk), continue to next step. Otherwise, you're done.
4. tap "Advanced", then "Reboot to recovery".
5. now sideload android12.1 gapps zip and/or magisk zip.

Thanks for the great work! I updated from 18.1 to 19.1, and everything is buttery smooth. The only issue I'm having is I'm missing the screen rotation icon that would appear on the bottom right corner when I rotated my screen in 18.1. I've been looking for the option to turn on "Rotate button on navigation bar" but cant seem to find it anywhere. Has this option been removed in 19.1?

Are you shure? I can`t find this setting in app.
