The app uses Google as the source for its address data. This means that when Google Maps is updated with a newly created property address, the address will appear in Antenno. Antenno works by sending notifications to whichever parts of the city are relevant for that particular information, so an interim measure can be to find the nearest address that does appear in Antenno (or even a street name rather than a specific address, although if doing this we recommend you choose a short street). We suggest this because generally nearby addresses will receive the same notification.
