+## Limitations
+- There is a bug in the Azure DevOps API.
+When retrieving pull request comment threads the position of comment threads is not returned correctly.
+If the incorrect position is out of bounds of the current version of the file, the plugin cannot place extmarks.
+Feel free to [vote to increase priority on the bug report](https://developercommunity.visualstudio.com/t/Pull-Request-Threads---List-API-operatio/10628358).
