USAA: Rich, we do not have a Windows Phone 8 app due to the low adoption rate, as this platform currently accounts for less than 1% of the total traffic generated to our site. We're evaluating the cost and effort associated with converting the old app to Windows Phone 8, but as a member-owned association, we have a responsibility to ensure that we are being good stewards of association funds. Frankly we need to see more people using this platform before we can justify the cost. In the mean time, please keep in mind that we continue improving mobile.usaa.com, which has been redesigned to give members quick access to USAA without having to download our app. -Lindsey
Rich: This is untrue. You do not have a WP 8 app because the WP 7 app needed to be modified in a minor way to work with WP 8 and not expose the possibility of a security breach caused by deposited check images being stored on the phone and SkyDrive. So you blocked the ability to install on WP 8 devices. This I can accept. But not making minor changes to the app to make it work, when the major work is already done, there is no excuse for. As a developer with apps in the Windows Phone store, I know this is not a difficult fix. Pulling the app from the store entirely, and preventing members with WP 7 devices makes no sense as it worked just fine and if you didn't want to improve it, you didn't have to.
As for using the mobile site, no. I won't. I don't know how you think removing an app that worked just fine will help you monitor WP adoption, or how you think that since you already blocked it from WP 8 devices you were going to track adoption, since the new devices being sold are WP 8 and would therefore not use the app.... Yes, I know you can get device type from the website hit stats, but as you've seen on other posts like mine, people just aren't going to use the mobile site. Since you made it more difficult to access my financial info, and you don't have branches, the thing that makes most sense for me is to move my money out of USAA.
As for justifying the cost, you did it with the Windows Phone 7 app, and WP 8 adoption has already surpassed that of WP 7, but you can't see that since you are blocking WP 8 users from using your app. In less than four months, WP 8 adoption surpassed WP 7 adoption, but you won't see it.
