Heyyo
@jeremywh7, ya caught me lol, yes I do have a LOS 19.1 test build up. It's pretty much what pre-official payton will be like. If you guys wanna test and report back? Please let me know
Thank you very much!

Did you want to start a new thread for it? If so I'll move this post to it later. ;-) Are you currently running 19.1, and if so what Gapps (if any)? Here are my notes on anomalies from my install (via sideload) this morning...
-I did a factory reset/data format in LOS 18.1 recovery, installed lineage-19.1-20220322-UNOFFICIAL-payton.zip, rebooted to recovery and installed NikGapps 'stock' [which is like OpenGapps 'Mini' but with Gboard, Dialer, and Drive, and without Youtube) and then their GoogleFi add-on. I 'Reboot to System' which apparently failed and sent me to recovery which told me I needed to wipe /data (again). It booted into setup after that.
-After tapping 'Accept' at the Google Services page, it had me set security (I did a pattern), but then it went into a constant cycle of going back to the Google Services page. Even after a another reboot.
-After this reboot, and all others since, I get a message after booting that says, "There's an internal problem with your device. Contact your manufacturer for details." Is this a new A12 thing - perhaps cuz our vendor image isn't current?
-After trying various things, I decided to do another factory reset/data format in LOS recovery. And this time I skipped setting the security pin/pattern/etc. Went through without a problem this time!
-Another bigger problem I figured out though, is that I couldn't use Home nor Recents, and Pixel Launcher (which replaced the stock launcher) would sometimes crash. I couldn't back out to exit (most) apps either, so the only way to go to another app would be through Notifs->Settings->Apps.
-I then switched to a different launcher (first MS' which I uninstalled 5min later...) to my old go-to, Lawnchair (2, now), which worked, except that the Home and Recents still don't work (and I still occasionally get Pixel Launcher crash messages). I suspect it's due to Pixel Launcher messing something up.
I think my Google Fi network issues might be fixed, but only went to the gas station and grocery store today.
Anyway, let me know your thoughts and experiences, and if you want any logs or anything (or want me to test any other builds). It's my primary phone, but I have no issue messing with it. ;-) And thanks for all the work on payton!!!
[Edit 11 Apr '22 - Google Fi does now work a-ok on this clean flash. I was out and about all day Sat and was on LTE the whole time.

I also uninstalled the /system Pixel Launcher using the NikGapps config file, which fixed the random crash messages from it. Still no Home/Recents, but the Feed works now. I was going to just wait for an updated 19.1 build to try, rather than reinstall the 0322 build. ]
