Galaxy A20 - BllocDesk Usb Debug dialog not showing up on device

i’ve recently receive ratio invitation, so i download the Blloc Desk for windows. after following all basic instruction to install ratio to step 3 (connecting device via usb) Usb Debug popup not showing up. i try to restart my phone and my pc, its still does not work. then i try to install Blloc Desk on my laptop, i still have the same issue, usb debug popup not showing up.

my pc using windows 7 ultimate 64 bit
my laptop use windows 7 home 64 bit
my device is Galaxy A20 (SM-A205F) Android 10 version.

i wonder if anyone knows to solve this problem :smiley:

Did you install ADB drivers first?

i think its automatically installed when default device usb driver installed cause i see “samsung adb diver installed” from notification bar, nor i need to install it manually?
