Hi all, yes - it is correct, that for variant A, no OTA update is identified.
I have found the issue and pushed a fix, which will be active, when the next build is created.
Sorry about that.
This means, that if you are on the January build, you have two options:
a. Manually flash the update via TWRP
b. My recommendation - please perform the following steps
Activate "Android debugging" and "Root debugging" on your device, connect your phone to your PC and enter the following two commands:
adb root adb shell setprop lineage.updater.uri https://raw.githubusercontent.com/lin17-microG/OTA/lineage-17.1/amami.json
