I just updated the RW app and discovered that the Data Tools button that I regularly use is now missing from the RW home screen. Instead, there are now 2 buttons (Manage my Data, and Add 1GB data now) that require login. Furthermore, it seems that these two buttons do the same thing after login–let you purchase data. And if you save your username and PW after using one of the logins, you still have to re-enter it for the other button.
I now have to click the settings icon to find Data Tools. I turn Data Freeze off and on several times a day and would prefer that switch to appear prominently on the RW home screen. Now we have two buttons on the home screen to purchase more data, and are missing the one that helps reduce the need to purchase more data.
