# Known Issues / Limitations

* `.exs` files don't return compilation errors
* "Fetching n dependencies" sometimes gets stuck (remove the `.elixir_ls` directory to fix)
* "Go to definition" does not work within the `scope` of a Phoenix router
* On first launch dialyzer will cause high CPU usage for a considerable time
* Dialyzer does not pick up changes involving remote types (https://github.com/elixir-lsp/elixir-ls/issues/502)
