I have seen many posts about this, and none of the solutions work for me. When attempting to add a domain to an app in https://www.google.com/a/cpanel/<my domain>/AddAppEngineService
I get the error: "An error occurred while trying to install this application. Please try again later." I have tried the Domain settings->control-panel->Current Release change as stated all over the internet, however this does not work. Also, under Application Settings -> Add Domain - I get the same error. It seems many many people have a problem with this. Is there any solution?
