After updating to Pie, my phone no longer receives callls. All calls go straight to voicemail without my phone ringing or showing any sort of notification. I can be looking at my screen when a call is coming in and there is no notification. There are also no notifications for missed calls. I can only tell that someone called if they leave a voicemail. This problem does not happen if the phone has just been rebooted, but after a few minutes starts to happen again. It is not a connectivity issue since outgoing calls work fine. It is also not a do not disturb issue or a blocked number issue. All other notifications seem to be working fine.
