I wonder if that means that if Adobe rolls out an update that doesn't work correctly (Hey, it could happen) that you can refuse the update or roll back to a previous version if you choose to. Or are you forced to accept the update whether you want to or not. Not sure how that works...
We haven't crossed that bridge yet - I guess the question could be restated -If an update doesn't work as well as an older version, can the subscriber/user "DOWNGRADE" to an earlier version?
I see no way on the Creative Cloud to let one back pedal to an earlier version on anything PSCC or LRCC. You are either up to date or not.
