I'm not sure if it is the Pixel 3 or the Android, but I got the same issue just after resetting my password. Now it asks me to re-login and wouldn't get anywhere after re-capture... just hanging. By coincidence my phone is also Pixel 3.
For example on my iPhone went through the same process - login, re-capture, and sending me confirmation code by text, call or email to confirm as it is not recognizing the device, which is weird as I always have been using this device, but at least got it working on my iPhone. There is some bug in the new code (app version) I guess.
I guess we have to open a ticket with Airbnb, not only post in the community...
