You can edit a existing location instead of adding a new location with a new address. However, you cannot delete a Location which has been already added to your Yapsody Account
Kindly follow the below mentioned steps to edit an existing location.
1) Go to Settings
2) Click on the "Location" option from the right hand side menu. It displays all the locations previously added by you. Select the location you want to edit.
3) You will see the options to edit Venue Title, Street Address and to select the time zone. Mention the new location address in the "Street Address" option and select the time zone for the new address. Click on "Save" at the bottom to update the new address.
Note : You can edit the location even if the event is published.
