Hello!
First off, thank you for working hard for creating an excellent app for learning Japanese grammar. My comprehension has improved immensely thanks to your team and your efforts in making this a useful resource. : )
Lately, I have not been able to get my Cram function to work the past few days. I have uninstalled and reinstalled the app in hopes it would work again. Sadly, nothing has come of it.
Otherwise, I enjoy this app and will continue to use it for studying Japanese grammar.
Thanks!
