We have seen this issue being reported by a couple of customers that when they want to publish their zenphi Flow which has a Google Forms trigger, the browser goes into a loop and eventually errors.
This happens because there is an issue with Google Authentication when you have multiple Google accounts signed in and trying to publish a Flow that starts on a Google Form submission.
To get around the problem, please open zenphi in an incognito window and publish it from there. It’s only necessary to do this the first time you publish the flow.
Hope this helps.
