We got email confirmation that our Cluster was upgraded to 220.127.116.1110907-135400. We found that there is a bug in the UI when editing the Application Settings.
When you select to edit a session property, you cannot save the edit, you must cancel then go back into the item and edit it, then the save button will be available.
Then I click cancel and go back in via Edit, we have the ability to save:
I have noticed that this occurs when the Request Attribute Name Fails to load the first time. Then clicking Cancel and going back in populates the Request Attribute Name.
Just a heads up as I don't think this is intended.
