I had installed this app several days ago and no problems until today. I am having the same issue as with the other posters, however what I noticed today is when entering my email address and then the password, the keyboard stays in CAPS for the password. After uninstalling and re-installing the same issue. Disappointed with the app, it was great when it worked and I really liked it. So I went back to the default HTC mail app, NOT going back to Gmail! Please fix ASAP. BTW, I have an Android device, HTC Rezound, Android v4.0.3
