I've sent for the WiFi router and it will be here on Monday but I've been impatient to get this thing done so I went back to the Apple Store at Destiny. I asked the guy in front, (a different guy this time) if I could use their WiFi to update my phone to 14.7.1 and he said I could sit on one of the chairs near the back and just press the link in settings to do it. He said it would take about two hours. It took about half that during which three friendly employees came up to ask if they could help. they answered all my questions. I also backed up to the cloud, (another update the phone wanted). I had several updates listed on the App Store that couldn't be done under 12.3. They were gone when I looked, so they must have been automatically done.
Then came the big moment. I went to the 'S" app and to manage tickets and to the Rutgers game, X'd off of the blurb about using Apple Wallet, then pressed the magic button...and nothing happened. No change.
I called a young lady who had offered to help. She pressed the magic button several times, for different periods and with different pressure. And nothing happened. She went over and talked with another guy, presumably her boss. He came over and worked with it for about 10 minutes. he observed that the website was weird, the bar code was strange and the blurb that prevents you from doing what it is asking you to do until you x out of it is the "stupidest thing I've ever seen".
He asked for my password and logged back onto the site - and suddenly everything worked. He added the Rutgers game and the Albany game to my Apple Wallet and gave it to me to do the rest. I've got the whole season on there now and my fears that I won't be allowed into the game are gone, (unless the bar code is too strange).
He made this comment to me: "It looked like we were on the right website but that wasn't it. I had to log back into it to get the real website". I didn't press him on what that meant but I suspect what I had was an older version of the SU website that has been redone for the current operating system and I've now got the current version of the SU site, which I could not have gotten without the update.
So now let's go and win some football games!
(If you go to the Apple Store, the big key is to get past the guy out front who says that they don't have anyone there who can help you. the people in the back of the store were not only cheerfully helpful but as happy as I was when we cleared everything up.)
