Whilst I would always acknowledge your greater knowledge Dave on such matters, my own understanding is that zoom meetings do not count for the purpose of section 85 other than under the temporary regulations, now repealed, for covid. Do you have a reference for this? When we had a similar incident some years ago (long before covid or zoom to be honest), a councillor tried to claim section 85 didn't apply as he'd attended an external event "as a councillor" but it was held, upon investigation by the MO and elections office, that as the councillor hadn't been asked to attend on behalf of the council, this wouldn't apply.
