It's stuck on this screen for a bit; if I manually enter the city, it works.

Still seeing failure prior to challenge screen which is another issue we're also debugging.

On local image built this AM & 10060.0.0 (logs attached for both)

Same failure for login_GaiaLogin btw.

[oobe]: Additional checks for GAIA webview.

There's an additional webview that was recently added for eula, so the
assumption that the only webview is the GAIA webview no longer holds.

 Issue 783137  has been merged into this issue.

Tested again on elm 64.0.3262.2 (built on 2017-11-10). The failure is still happening.

For me, the stack trace is slightly different (full stack trace is as per  Issue 783137 ) - it ends with:

TimeoutException: Timed out while waiting 60s for py_utils.WaitFor(lambda: not self._GaiaWebviewContext(), 60).

but the symptoms are the same as above. As above, if I manually enter the city, it is able to proceed past the login screen.

Just launched a second power_LoadTest on a different device (same build). This time, it succeeded without needing to manually enter the city (although there was a warning about a previous suspicious sign-in).
