Can't answer calls from drop down
Lately, I started having a problem on my Priv. When a call comes in, if the phone is unlocked, the drop down notification will not respond to tapping Answer or Dismiss. To work around the issue, I went to Settings->Sounds and notifications->App notifications->Phone and turned off "Allow peeking". This disabled the drop down and brings up the full screen slider to answer.
I would prefer to be able to use the peeking notification. Any ideas? I'm not sure exactly when it started, and there have been a lot of app updates lately.
