Vey good rom, with many useful features. Just one question, why my internal storage is only 19GB? It has happened again to me on another device, I do not remember what I did exactly, can anyone help?
And something else, I cannot root my device. OF course I've installed TWRP, buy neither Magisk nor SU or anything else will work. My magisk says "Magisk in installed as system app and it's not supported, turn it to user app". What does it mean? Thanks!

    The last phone I had rooted was an LG G4, I haven't done this for many years! lol
    So I will keep this one the FM radio is important to me. The problem is that I cannot root it. Back in my days, we used to flash the SU via TWRP, I see ow that Magisk is used. The Magisk is installed along with the rom, and I get this message to revert it to user app. Isn't there any way to flash the root files via TWRP? Thanks!

    you can use TWRP's internal file manager to remove Magisk from /system/priv-app, though it's weird as I don't recall the latest version having Magisk automatically install but I'll see
