Phone is used for smart lock; this has worked for past year or more. Now lock screen says it can't find phone. Phone Bluetooth is enabled and works with other devices. Phone is within inches of Chromebook. I tried deleting the phone from the list of paired devices and re-pairing. Re-pairing went as expected and phone re-appeared on list of paired devices, but again it says "Not connected".
