I am sorry to hear you are having trouble changing the Organization Address in your Wordpress form. To update your address, you will have to update it from your Wordpress account for it to take change. In the case that you need additional help in regards to your Wordpress integration, we have a specialized team that works with this integration available by phone.
I apologize for any confusion our previous answer may have caused. Has the address shown in your Wordpress plugin updated? In cases where the organization information has not updated after being changed on the My Settings page, we have seen it change after 24 hours. This is something we are looking into further. In the meantime, as a workaround we suggest waiting 24 hours, and then check the website again. After this 24 hour period, the address should be updated. If you have any further questions about this please reach out to our Support Department directly. We have a team that is specialized in this Wordpress plugin.
