The old app just shut down on me and forced me to download the new one, and then gives the option to either sign in or transfer my account from the old app. I try to transfer my account, but it won't go past the store selection page, and won't give a list of any stores to select. I try to log in, and it says the account doesn't exist. So now I can't use either app, and I have no idea if I'm going to lose my existing rewards or start from scratch again. Stupid.
