TalentNest's address field uses Google Maps to auto-fill addresses.
If you are getting an invalid address error, your exact address may not be recognized by Google. This may be due formatting of your address or perhaps Google has not properly mapped your street yet.
Google Maps will try to suggest an address as you begin typing. If your address is one of the options listed in the drop down menu, click it to save time and auto-fill the rest of the address field.
At a minimum, you should be able to enter in a Street, City or province into the address field and that be accepted.
