Uninstalled due to inability to log in. Previously, I could log in and access the information, but since the update, I can not even log in. The app attempts to log me in, but then errors pop up and I am returned to the log in screen.

Very convenient and faster than using the usually laptop method. Can't do everything with a laptop with the pod method but this is great for quick little things!
