We have recently started a new project and wanted to give it a specific key, lets say ABC. When we tried to do this we got an error saying that key is used by project "A Bee Circus". This project is old and "abandoned" since a while back, so we changed that key to say "COB", something completely different. However When trying to give the key to our new project we still get the error that is't being used by "A Bee Circus", even after waiting a few days for the change to take affect. Is there a way to solve this or are all old keys eternally blocked?
