I see the previous problem in this question, because if you have set the 'neighbor' statement under router ospf process. It will disappear after setting 'ip ospf priority 0' under the interface. However, it should not be called 'incompatible' ... It should be called 'unnecessarily' after that.

I used to put "ip ospf priority 0" under interface on spoke - to avoid any possibility of electing spoke as DR.

In this case "neighbor" statement doesn't really work on spoke.
It doesn't appear in config even.
However it works (placing "neighbor" initiate sending of 1st unicast hello packet towards to Hub) until You reload spoke router . So If You put "ip ospf priority 0" on spoke, put "neighbor" on Hub.

I don't know the explanation why "ip ospf priority 0" and "neighbor" under ospf process are "incompatible"
