I received the following error when trying to install a new add-in for Data Lake in D365. "Validation failed. You must be an environment administrator in Microsoft Dataverse to perform this action". I received this error after we registered the Microsoft Dynamics ERP MicroServices application in AzureAD. Earlier in the day, I was able to see the next window that asked me for the application ID, Tenant ID several other pieces of information, that was before the application was registered. I am a project owner and the environment is Tier3. We also had a user who was an Environment Admin, but they received the same message. I am also a global admin because we have added permissions to eliminate that as an issue. I am confused as to what might have happened to remove these privileges.
