Beginning I think with version 0.41, the UI would not load on Home Assistant when the service was restarted. I narrowed it down to my pushbullet configuration. No errors were logged, the UI just refused to load.
Removing these lines from my config fixed the issue:
#notify:
# - name: PushNotifications
# platform: pushbullet
# api_key: Mysecretkey
Any thoughts on this?
