I installed Lineage 18 on a Pixel 2 without issues. I followed the official guide (https://wiki.lineageos.org/devices/walleye/install).
The problem is that there is no Play store after the first boot. I wiped again twice and redid everything without issues. Still no Play store and firstboot is normal.
I tried to wipe, install lineage, firstboot, then boot to recovery to install the gapps.zip, but of course that expectedly created problems (system not booting, sending straight to recovery).
I tried gapps nano and pico, same thing.
I'm out of ideas, any help will be very welcomed. I flashed multiple devices in the past and never stumbled on this issue.
Could that be a a-b slot thing? I doubt adb sideloading lineage and then gapps right after one another would send one to A and the other to B. Maybe MindTheGapps would behave differently?
Thanks in advance for any help.
