+### Intermittent data retrieval issue with LookUp using the Snowflake Connector v2
+
+Intermittently, lookup queries against Snowflake return no values even when results are expected. No errors are generated, and the lookup activity completes successfully. This issue has been observed with Managed VNet IR and SHIR.
+
+**Workaround**: Add an If-condition activity after the Lookup to check its output. If the Lookup returns data, proceed without further action. If no data is returned, re-execute the Lookup activity.
