Might be useful if it doesn't always log me out all the time. I try and log into the app hundreds of times and it won't let me log in. Yes, I have changed my password and have done all that I could to get in this lousy app. Now I can't play Magic at my local games store thanks to this stupid app. This is because this app is REQUIRED if you want to play against other people. Seriously Wizards of the Coast, fix your apps!
