Chromebook Settings lists only my OLD phone for connection, not my current phone Spin 13 CP CP713-1

I received my Spin 13 CP CP713-1WN-53NF about a week ago.  In the Settings, it gives me the option of connecting to my phone.  But the dropdown list of phones only lists my old Nexus 6 phone which I replaced a month ago with a Pixel 4a.  Of course I want to connect with my current phone, not my OLD phone.

The Chromebook and both phones use the same Google account.  I use the (old) Nexus 6 on WiFi, but it does not have cell service; only my (current) Pixel 4a has cell service.

How can I get the Settings to "see" my current phone?

Thank you for any insight!
