Hi All,
Thank you for reaching out to the Google Ads Scripts Team. Please excuse us for only getting back now as your message failed to be routed to our support queue.
I would agree with Nils' statement. I'm afraid that there isn't a way to go back to the old or legacy version of Google Ads Scripts as, moving forward, scripts would now default to the new script experience <
https://developers.google.com/google-ads/scripts/docs/start>. If you haven't migrated your scripts yet, I would advise that you do so that it conforms to this current version also so that they are functioning as expected:
If you do have any clarifications or encounter any errors, do let us know so that we may be able to investigate and guide you accordingly.
Best regards,
Google Ads Scripts Team
