The only fix i found was to get an old APK fro the 1.4.6 version. LOL
luckily my Gtab 7 had it. I backed it up using my back up pro and saved it to my dropbox file. Installed it on my GS3 and works great. The new 2.xx versions are still way buggy in my opinion. I too was like you and uninstalled it, reinstalled the new version, cleared memory and logged in and out several times.
