 ## Known issues and limitations
 
 - The following `QuerySet` methods aren't supported:
-  - `aggregate()`
   - `bulk_update()`
   - `dates()`
   - `datetimes()`
   - `distinct()`
   - `extra()`
   - `prefetch_related()`
 
+
 - `QuerySet.delete()` and `update()` do not support queries that span multiple
   collections.
 
+- `aggregate()` Sort with aggregate may not work well.
+
 - `Subquery`, `Exists`, and using a `QuerySet` in `QuerySet.annotate()` aren't
   supported.
