Project members see "Ready to be Merged". Where as the admin’s view says "Rebase the source branch onto the target branch or merge target branch into source branch to allow this merge request to be merged." ### Proposal Make it clear to other team members that the merge request needs a rebase. ### Links / references Project members see: ![rebase-user](/uploads/902773ecb9f2cd98e1fb02a4386fab54/rebase-user.png) Admins see: ![admin-rebase](/uploads/098a67b6f3217a0eaca0bdaea9ae905b/admin-rebase.png) https://gitlab.zendesk.com/agent/tickets/65178 https://gitlab.zendesk.com/agent/tickets/70982
