As in the title, I successfully upgraded our on-premise instance to version 16.9 but the project members’ authorization doesn’t work anymore. If a user has access to a project, he can still view or interact with it, but if I add a new member, he cannot see the project or sometimes he can see the project with a direct link but he cannot push code even if he had the Mantainer role.
Ok, it seems related to Sidekiq because it’s not running and all the authorization jobs are pending. Here there is another open topic:
