2.After service instance is ready, on provisioned service page, update first plan to second plan by "Edit" button.
3.After close the update panel, wait the status become ready, check plan info on provision page.

Actual results:
2.It updates successfully.
3.It still show first plan, second plan shows up only when we refresh the page or access other page then access provisioned service page again.

Additional info:
If update parameters on "Configuration" stage, it will show the updated parameters immediately, no need to refresh.

PS: if the issue comes from lack of watch of this resource? we also found that seems no watch of quota in quota page, no watch of secret in secrets page until fresh
