I recently received 3 Class B authorizations for 3 consecutive days in a zero LAANC cell to 90ft AGL to give me a good chance of having good weather on one of the days. The first day (yesterday) turned out to be beautiful weather for flying, and now I would like to cancel the other two unnecessary authorizations but do not see a way to do that in the DroneZone "Manage Waivers and Authorizations" section. You seem to be able to cancel a submitted authorization application before it has been approved, but not afterwards. Does the FAA or ATC not care whether or not you use it once approved?
