I don't know if anyone else has experienced the problem I have, but I'm giving you a heads up. I'm out of town for the next month and wanted to change the default shipping address to another location other than my billing address. If you don't change the default shipping address on the AppleID site, no matter what you type in on the Apple Store, Apple Store app, it will default to that address on the ID site. I forgot about changing it and every time I'd go to the AS app, the default shipping address had reverted back to the wrong address, even though I had just changed it in the app 15 minutes prior. After wasting a couple hours making sure my address is fixed so I can easily and quickly check out tonight, just wanted to save anyone else the headache I've tried to figure out today. Anybody else using a different address other than your default billing? Worried about any order problems? Hope all goes well for everyone tonight (tomorrow).
