GreenMerge automatically merges green pull requests with one accepted review
It is performing the default behavior of the merge button (creating a merge commit).
If someone submits a pull request to your repository and you accept it but the code changes before the check suite is finished, then your review will be marked as stale by GitHub, so GreenMerge won't merge it.
You can visit our app's configuration page in your GitHub settings and edit the applicable repositories.
GreenMerge will only merge pull requests with one accepted review, so you will need to ask someone else to review it, or merge it manually.
Feel free to submit issues or suggest new features by creating an issue on our dedicated GitHub repository
