I setup a new D365 F&O instance early this week with 10.0.23 (10.0.1037.53) version.
Later noticed an update available - 10.0.23 (10.0.1037.84). Tried updating to this version, which keeps failing repeatedly.
Although the progress shows all steps completed successfully - 73/73 steps completed - the status always ends up in 'Failed' state -
Servicing this environment has failed. Please click the Resume button to retry the failed operation.
