 ## Retrieve bulk data on demand
 Use **getRetrievalInstructions** API in `005: Dataset Service collection` to retrieve bulk data from external data source on demand. 
 
-## Known issues
-- Below issues are specific to [OSDU™](https://osduforum.org/) M18 release: 
-    - EDS ingest DAG results in failures when the data supplier’s wrapper Search service is unavailable. 
-    - EDS Dataset service response provides an empty response when data supplier’s Dataset wrapper service is unavailable. 
-    - Secret service responds with 5xx HTTP response code instead of 4xx in some cases. For example, 
-        - When an application tries to recover a deleted secret, which isn't deleted. 
-        - When an application tries to get an invalid deleted secret. 
-
-## Limitations
-Some EDS capabilities like **Naturalization, Reverse Naturalization, Reference data mapping** are unavailable in the M18 [OSDU™](https://osduforum.org/) release (available in later releases), and hence unavailable in Azure Data Manager for Energy M18 release. These features will be available once we upgrade to subsequent [OSDU™](https://osduforum.org/) milestone release.
