Your agent is now in Extended mode so once you get it back online, it should be fine but remember that you canceled your subscription so at the end of the month, it will fall back into Prestaging. At that point, you can renew or just leave it until you want to use it again.
Prestaging is when you're getting your agent ready for a subscription.
There's no point in purchasing a subscription until your agent is properly communicating.
It's a way to make sure people don't waste their time and money buying a sub for an agent that's not correctly communicating yet.
It's not really a bug but a logic thing that we thought we solved :).
