Set up system, worked for a bit, then Power Outage until I upgraded

I set up my system and everything was working fine. Did not have the upgraded plan. A few hours later, I see in-app "Power Outage" except there is no power outage at my home. I trouble shoot, the customer service person says they'll send out a new power adapter. I upgrade my service to the $24/mo package and miraculously the system's "Power Outage" notification is GONE! Is this seriously a way for the company to make additional dollars to get everyone to upgrade?
