Guys, used to flash this ROM as well as recent Magisk and pico opengapps; everything *seems* so far fine but I can't get through the setup as google play services seem to continuously crash before creating an account. Anything to do about this? Help really appreciated. gapps arm (not arm64) is right?
Answering that myself, apparently it was my mistake. I wasn't aware AOSPEx on this device ships with Magisk and so I tried to flash Magisk 13.2 all along with the ROM itself which *seems* to have caused this behaviour. Just flashing the ROM and bean-gapps worked well. Now only to figure out how to use the "stock" camera app on this ROM...
