I think I know what the issue is. I have the $35/month Simple Start, and this requires the $75/month Essentials plan, right? But not necessarily Time Tracking. (And why is there a Time feature and a Time Tracking feature and they're both different things?)

I guess I have to decide if the doubling of my subscription is worth it, or if there's a slightly cheaper third-party solution that will do the same thing.
