Yes    

The `cluster-observability-operator` is not getting auto upgraded when operator version in the stable channel is updated.    

The operator should get auto upgraded when operator version in the stable channel is updated.    

ISSUE SUMMARY - 

1. The Installer/Bastion node was initially installed with RHOCP version 4.14.26 . the Mirror/Upstream channel was updated with COO version 0.3.0.
2. Cluster Observability Operator (COO) was installed with version 0.3.0 on the managed cluster.
3. The Installer/Bastion node was upgraded from RHOCP version 4.14.26 to 4.14.37.
4.  Post-upgrade, the Mirror/Upstream channel was updated to reflect the latest COO version 0.4.0.

5. There is no "stable" channel available for COO in the upstream, and only the "development" channel is present for version 0.4.0. This is what is mirrored.

6. Despite the latest COO version (0.4.0) being available in the upstream catalog, there is no Install Plan (IP) created for cluster-observability-operator  version 0.4.0. in the Managed Cluster.

7. As a WORKAROUND, the existing Subscription, ClusterServiceVersion (CSV), and InstallPlan (IP) were deleted. After this, a new Install Plan for COO version 0.4.0 was successfully created.

Need to know Root Cause why the Install Plan for COO version 0.4.0 was not auto-created  even if upstream channel was updated with 0.4.0 post bastion/installer upgrade from 4.14.26 to 4.14.37.
