Yes I think most COBEs are all follow the direction to be pro vax. I don’t think any will forget direction. Once some direction is in place that is the way things are done unless further direction from the GB.
So if only the CO has had this U turn direction then he has to tell all congregations individually before next KM school.
All those elders who were not allowed to attend because they are not fully vaccinated will assume they can’t go to the next one either unless they hear there has been a U turn on the policy
