annoying sound Notification when exiting unlock screen

Recently updated to Key2 from KeyOne and overall satisfied. One issue with my Key2 is a annoying Notification sound everyone I wake my phone or unlock it. Cannot figure how to remove the sound. Even occurs when in Priority mode (where only alarms and calls should come through). Anyone else experience this (never had this issue on KeyOne) and any solution. Thanks

Settings\Sound under other sounds and vibrations toggle Off "Screen locking sounds"

Thanks for reply but I have that off already and still makes the noise (did turn it back on and off to see if that worked).

Hi any updates regarding this? I am having the same issue after resetting it

Do a 32 second reboot
