TimeCamp Integration

I installed the TimeCamo plug-in for Chrome and an icon now sits at the top of the screen. I clicked on it to log in and enable the link. I still do not see a button in any Asana task to start or stop a timer or send completed time to TimeCamp. When I look at my profile and click the App tab, I see TimeCamp listed as an authorized App but it is not listed as available. How do I make it available? I have previously linked to Harvest but I deactivated it and unauthorized it, The listing under authorized vanished, but Harvest still displays in Active.
