I would do it this way, changing email address on an account is stupidly difficult with city, took me 3 months to separate mine as I used my address for my kids season cardsI’ve not done it your way but you can transfer Daughter 1 ticket to your account so you own the ticket.
You then get an email with the link to the e ticket attached that you can download to your wallet. It might be easier to Just forward that email to Daughter 2 email and she can download it onto her phone and it goes in her wallet.
Ive done this twice this season to bring people who don’t have a supporters number.
