Today, my HTC 10 was updated to Oreo 8.0.0.
Now, whenever an app requests my location, I get the location icon appearing, and a default notification sound plays. "System UI: Finding Location" is what the notification displays.
The sound never played before the update.
I've looked everywhere to try to turn this notification sound off, and I cannot find it.
I did go to Settings > Sounds and Notifications > Advanced > Notifications. When I see the list of apps, I've also clicked on the options menu to include System apps. I assumed I had found it with Location Services, and turned off "Allow Sound" which was turned on. It did not turn off the sound. I also restarted the phone.
I would like to turn off the sound while continuing to allowing apps to request my location. For example, when I go into Instagram, or the camera, I get the notification. I don't care if it shows me the icon for a second, but the sound has got to go.
Edit: Verizon Wireless is my carrier. I didn't think that was relevant, but once I found the solution, I realized it was.
