This doesn’t seem to have worked.
I created a column in the google sheet on the home tab for “NoProfile” with a false set check box.
Then added an if then else to the profile tab in the data section of glide, to show false for everyone without an email address.
In the home tab in the glide data I added a relation multiple column between NOProfile column and the true false profile column.
Then created a lookup column in the home tab in glide that referenced the email in the relation column.
I’m not getting any of those columns on the home tab fill with data, and there’s no front end effect in the app when the visibility filters are applied - It doesn’t react to which email address I’m previewing as.
