after adding my android package name in the basic settings page unser google play store platform , and then saving the basic settings page it reloads then the page is not visible anymore , it only happens just after i add my package name for google play store platform . Now i can retrieve my app secret anymore.

Another thing i noticed that in the browser console that before add any platform and saving the settings there were not errors but when i add a platform and save the settings the page reloads then few erros show up in the browser console stating some if their modules did non fire due to missing dependencies.
