It’s not currently possible to use Google Address Autocomplete with our Discreet House Number and Street Name Address Fields feature.
This is primarily a UI/UX issue. Using either House Number or Street Name for the autocomplete creates issues as it isn’t sensible to type the required info for autocompletion into either field.
The only solution would be to have a separate address search field, which is not ideal but would solve the issue. We may add this in the future, but for now you must choose which feature to prioritize.
