I want to reiterate how terrible this app is. Multiple coworkers and I have used this app and it has begun to randomly reset itself again after this latest update.
One can sign in to your account and have everything working and then at some undetermined time in the future youll stop receiving e-mails. If you then open Touchdown youll be presented with the account setupn screen, because Touchdown will have wiped all of your data.
The fact that theyre charging for this utterly broken app is shameful.
Old Review (Another broken release):
When Apple released iOS 8 it fixed a few issues with this app in the proir version (namely, deleting of the client certificate and opening the app and not being prompted for your pin).
iOS 8 did however break the push functionality of TouchDown...
But then NitroDesk decided to patch for iOS 8 support and re-instate all of the previous bugs. Again this app deletes my client certificate (at random, even they admit its a bug and couldnt say when it would be fixed). Again it wont prompt me for my pin unless I navigate around the app for a bit. Push works, though. So for the few hours to few days before the app seems to have a memory issue on shutdown and decides to delete your client certificate, it "works" in that it basically doesnt at all but returns to the previous state of affairs.
Literally the worst app Ive ever purchased.
