The app is terrible. Most of the time when u try to open it, all I get us a blank white screen. I have tried talking to dupont who offer the same 3 options such as close the app and go back in, Uninstall then re download, or restart my phone. Whenever I tellthrm I've done all three they either tell me to just wait it out (it can take days!) Or they close the chat... so just a heads up! Good money when and IF the app works.
