How to turn off Test Mode
Turning off Test Mode is relatively simple. These are the three steps to do it:
Go to https://forms.google.com while logged in only as the installer of the add-on, and open your Google Form in Edit mode.
Look for the puzzle piece in the top header tool bar to re-open your Add-Ons.


The Payable Forms Sidebar will open and in the sidebar, switch Testing Mode to "Off"

If you receive an error at this point, it is most likely due to multiple Google Accounts being logged into the same browser, or a mismatch of the original Installer account and the one you are using now. In this instance please open an incognito browser window, sign in only to your form's Google account, open your form and try again.
