+    <!--
+        Fix M2.4 introduced bug caused by new interface implementation.
+        New interface implementation checks against in-store reserved stock.
+        This in turn throws an error as this functionality is disabled.
+        Approach is to revert back to original implementation as new implementation errors due to redundant code.
