Today I actually tried for the first time to follow and thus test the FPOOS update guide.

Basically it worked fine, except for that I didn’t manage to use ADB in TWRP:

TWRP Experiences, Pros & Cons

Does anyone else have problems using ADB in TWRP? I just stumbled over this today. ADB works fine when running FPOOS. Then I went into TWRP. ADB devices finds the phone, but the computer suddenly does not have authorization to use ADB. After booting again into the OS, ADB works again as just fine. So apparently I have no authorization to use ADB in TWRP, while it works fine in the OS. Is it necessary to give an extra ADB authorization within TWRP?
