I had a problem after creating both the APIs in the Google Developer Console and enabling the GCM service, but I want to add the server key in Credential next to the API in the menu on the left. But it shows me. You do not have sufficient permissions to view this page. Below is the image: 
Is this some kind of configuration I need to add? I made sure that you do not have sufficient rights to view this page to clear the cache and use incognito mode to log into the system, but it still does not work.
EDIT For a while, I redirect it back, when I click on the other side and click back, it shows an error again, and my decision goes to Credential , than using the upper right corner of the account to log out and redirect, let it redirect you back to Credential than works. So, is there any solution for fixing it permanently without relogin?
thanks
