Cannot log in

Good evening,

I am trying to use one of the quick-start templates and I am receiving the following error:

```

Traceback (most recent call last):
File "my_quickstart.py", line 34, in
with smart_run(session):
File "/home/username/anaconda3/envs/instaplay/lib/python3.6/contextlib.py", line 83, in __enter__
raise RuntimeError("generator didn't yield") from None
RuntimeError: generator didn't yield
```

Start by reproducing the failure from my_quickstart.py, especially the smart_run call at line 34, and inspect the generated /tmp/20201029-153951.html file. Trace the login flow reached after the session starts and compare the timeout messages with the template's expected behavior. Done means the quick-start template completes login without the reported timeouts and RuntimeError.
