After changing my password, I couldnt connect anymore to my account (and it looks like you have to be connected to contact support!). The app kept telling me my credentials were wrong. Eventually I changed my password one very last time, deleted the app and reinstalled it, went through the initial logging again and, lo and behold! Its back online! This is very frustrating and shouldnt happen...
