I have a Pixel 2 XL on Android P.
I am unable to get the Phone Ringing Event to fire at all when I receive calls. I have the volume on and am calling from a phone with a custom ringtone set. The UI of the app shows no activity when I receive a call, and the run log is completely empty after calling myself multiple times. The task that should fire simply sets a variable to 1 for now.
Please let me know if I can provide any other information to help debug this issue.
