I have been using this app for a long time. I rearranged the app icons under the app menu icon (3x3 dots up by my picture) so that the GV app was easily accessible. I did this for the 2 different gmail accounts as I have 2 OBI200s. Everything has been working fine.
Now ... I tried to add the GV app to my brother's gmail on his computer as I set up a OBI200 for him. But the icon is no longer available to add? There is a different app now available, but it installs an icon on the address bar, has limited flexibility to associate it with different gmail accounts, and has a different interface. Anybody know how to access the old GV app and add it to the list of icons under the app menu icon?
Your question does not appear to have anything to do with OBi devices or services.
Perhaps you should ask on one of Google's forums.
