When a plan is created or edit, it takes forever to finish the process. I am now waiting over 8 min. for the process to finish when I hit the final next to go back to the plans page. I am not sure if its locked and gets stuck but this has been going on for a long time. Just to edit a plan its just a very frustrating waiting process.
I tested this same option on the 2nd cluster and it took no time to edit a plan and was done in seconds.
