Sorry, I got nothing. I have thought it out, but it was not something I was really concerned with.
Hopefully, if you are voting on a Bible app, you would be honest
But, some thoughts - this would only work if you made them SIGN IN with email.
Not sure how this would work, maybe someone reading this …
But, if you could make an IMAGE that connected to the FORM then count how many times that email ‘voted’ - the made the image disappear when vote total equaled ONE. Using some formulas and an IF-THEN column.
I know there is something like that in that ‘concepts’ app.
