I have been using Google Cloud Platform mainly to use it with Google Maps. I created several API keys which are working fine. The last one was a couple of weeks ago. A couple of days ago I wanted to updated it but couldn't, an error message was coming up very briefly when saving it.
I thought it might have been a glitch for that day. Today I tried again and I got the error again. The error says "You don't have permission to edit this api key. required permission serviceusage.apikeys.update"
To make things worse I can't update other API Keys neither.
I guess something has changed but I don't know what, any idea ?
