Google Maps isn’t perfect. Sometimes the address autocomplete on Brandibble, which is powered by Google Maps, won’t recognize the address as you've typed it.
This could be due to the fact that the address you're trying to enter may be listed differently in their database, or it may be missing entirely.
We would suggest slightly varying the way you’re entering the address or entering a different address that’s very close by. You can also report an error to Google here:
Hope this helps! Brandibble unfortunately doesn't have any control over this, and while Google Maps isn't perfect, it is the best solution out there.
