The About Screen in OnCue has some helpful information you should know about.
The first thing is the version number so you can be sure you're on the latest. If you're not sure, you can look at what you have and compare it to the Update History which will always have the latest build on top.

Last is the day your subscription expires and either auto-renews to your credit card or manually renews with an invoice payment for our check customers.
