This rom still has the initial pie build of October. Isn't the rom development active ? No updates since then. Currently am using pe pie rom only but from different maintainer named silent_27 from a russian website named pda. It receives updates from weekly to fortnightly. It is great actually. The only problem being everything is in russian from their website to their telegram channel and there's no xda thread for it.
Hmm..you made me curious lol. I installed this rom from your link.
PixelExperience_go_santoni-9.0-20181218-1919-OFFICIAL.zip from silent_27 . Like it so far. Sad that there is no thread for it. Very smooth,no bugs so far.
Did a clean flash. Magisk 18 didnt work for me. Using 17.3 now. Nice Rom. Thx for sharing.
