"Log In" button does nothing in the Android app

What is the issue?

Tapping the blue "Log In" button in the Android app does nothing.

Steps to reproduce

1. Install the Tailscale Android app from the Google Play store
2. Open Tailscale app
3. Tap OK in the Connection Request modal
4. Tap "Get Started" on the onboarding screen
5. Tap the "Log in" button

Nothing happens except for the button animation occurring.

I've tried uninstalling and reinstalling the app, as well as clearing the Storage and Cache for the app.
