I’ve encountered a issue similar to what’s been described here. Working off the Instagram template, I have a form set up to allow new users to complete their profile to provide additional info. In the Instagram app, nothing gets written to the Profiles source sheet until a new user fills out that form. Once they do, it populates as below.
In my app, once a new user sign-up, their user email (only) gets automatically and inexplicably sent to the User_Email field in that sheet. A few rows are also skipped. When they update their profile, a new row is created with their email duplicated.
I’ve recreated the tab in the app and the sheet itself three times using different column headings and tab names - same result. There is one array formula in the First/Last name column.
The setup for both apps is identical as far as profiles go.
Any idea why this would be happening?
