I'm having problem updating Magisk on my Gemini. I have a fresh installed rooted android 8.1.0 with Magisk manager 7.4.0 installed but when I try to update Magisk from 19.1 to 20.1 the installer finish but after reboot I'm still at version 19.1.
https://pastebin.com/sFH4GzjzI also tried to install the file from twrp but couldn't find it since twrp had problem mounting the file system.
Not sureif this is a local problem or a problem with 8.1.
