"Last Launched" meaning in Device Activation Limit window
We use Acrobat for PDF editing with my company, and recently my coworker tried to use a license for a new user and got the Device Activation Limit window. I said to kick off the one that says it hasn't been launched in 3 months, since they haven't been using it, but coworker says that date is the last sign in not the last use.
That obviously doesn't seem right (the help documentation itself uses the term "launch" to mean "launch an app") so I wanted to confirm. Is the date the last sign in, or is it the last time the app was launched?
