This is still an issue for me in March 2018.
I cannot load my watches, so I cannot use the App.
I have no luck in AS app or in a Safari page in my iPhone 6s, now running iOS 11 and updating the Auction Sniper App.
Update as well, I also cannot even do it on my laptop! Ack
I CAN download my current “won” items on Ebay via the “Wins” column in the App.
It can access my won snipes from before 12/29/16.
Is there any possibility this is a setting in Ebay??
