As a workaround, you should include the architecture in the tag name of individual images. For example, use `mygroup/myapp:1.0.0-amd64` instead of using sub repositories, like `mygroup/myapp/amd64:1.0.0`. You can then tag the manifest list with `mygroup/myapp:1.0.0`.
+### The cleanup policy doesn't delete any tags
+
+In GitLab 13.6 and earlier, when you run the cleanup policy,
+you may expect it to delete tags and it does not.

+This issue occurs when the cleanup policy was saved without
