Leader Qr Codes...retroactively

Is it possibly to retroactively assign "leader" QR codes?

The CSV file we uploaded has "teacher" as a column, but I failed to generate QR codes for those prior to photographing the school. Can I manually assign them, somehow?

IN theory you could go ahead and create the QR codes for them.  Then edit those group photos after they have been uploaded and set the title / password to the passcode created for the QR code.

When I click "create group codes" it gives me only these two options displayed (there are actually 10) and then I don't have the "create groups" button option like displayed in the manual.

I'm guessing I need to do it differently since I'm creating them retroactively?

The problem was with an apostrophe in some of the leader names. I created a  fix and uploaded it to your site. See if it works now.

That did it! Thank you so much!
