Ally and USAA have both pushed updates for their Windows Phone apps, unlike the others who have ended support recently. Both updates bring along fixes for various bugs, which is always welcomed. Users had reported having issues with logging into the USAA app, which has hopefully been addressed in the latest update.
Both updates are live in the Windows Phone Store, so if you bank with either of these companies be sure to grab the update.
Thanks for the tips, Frank O. and Mark W.!
