I noticed on my new install of PCS 9.0R3.1 that the "Activate" button is no longer available when selecting a different ESAP package to make active. I did notice that selecting the radio button of the ESAP version of choice and clicking the "Save ESAP Changes" button does in fact activate what you select, but it's not like it used to be - and not very intuitive either. The 9.0R3 admin guide still has instructions to click the Activate button. Woops
Thank you for letting us know that we missed updating the admin guide The change was intentional to make it more intuitive to apply to both activating the new ESAP as well as updating the ESAP version to be used on the client; apologies that this backfired.
