We are no longer able to associate our Apps Script projects with our Cloud platform project. When going to Resources: Cloud platform project in the GAS editor, and entering the project ID, it says "Project doesn't exist or you need Edit access to it.". The project definitely exists and the same Google account is an owner of it. With the same workflow, we previously managed to associate many projects.
Is there maybe a limit on how many GAS projects can be associated with one Cloud project? We've associated about two dozen recently, and then it started to produce this error. Or what could be going on?
