Get the app. As soon as I go to "manage tickets"- I get access to both of our tickets, and I can put them in my "wallet". There's also the option of selling or transferring the tickets as well.
I got the app. I could only download one ticket at a time, each taking several keystrokes. Then I went to get the next one. I had to go about about 4 or 5 screens. 2 seats for ~20 games - that got old real quick.
A person with more than two brain cells to rub together would think they would have a provision for season ticket holders to download all their seats in one fell swoop, Then if you did want to transfer/sell one or more you could deal with those individually from your wallet.
