Has anyone had problems with the app recently?

I practice Rocket Korean pretty much every day from my app on my galaxy S 3, but for the past few days the app won't work. I've tried uninstalling it and reinstalling it, but nothing works! Has anyone else had this problem?

Hi Sgrace28, We had unexpected problems with the app when the new members area layout was introduced however it should be working again now - please let us know if you're still having issues!
