Key is "hello world" and no notification audio

[Nateowami]

The first time I installed it, all it said was "your key is 'hello world'." (A review on Google Play reported the same problem). I tried opening and closing it several times to no avail.

After removing and installing it again, it works, and notifications are sent. However, they don't always arrive (even when it says they have), and no sound is played for notifications. Sometimes it vibrates.

Are you able to reproduce these issues?

I'm facing the same issues with sound and vibration for notifications.

For some reason, I'm also not receiving sounds or vibration upon notification. Hopefully, this will be fixed.

Audio issues should be fixed.
