Azure Repos — Warning: Multiple merge bases detected. The list of commits displayed might be incomplete — Solved
There are no merge conflict displayed, but warning message is displayed.
Oct 6, 2021
How to fix:
Take the latest changes of destination branch to source branch and complete the merge, after that this message will not come up on the pull request page.
In my opinion, this is good that Azure DevOps is giving such a warning so that if you forgot to take the latest from the target branch before finishing your pull request and it may save some time or end moment rush & surprise.
