I Hope I'm Wrong

What happens if you lose internet connection to your Ring Alarm system for more than a day?I've just got off the phone to someone in Ring Technical Support and they say that the system will NOT give off an audible alarm (either basestation or outdoor siren) if it loses connection for longer than 24 hours.Surely if this is true it's a major design flaw!?! Before anyone jumps in to mention the internal cellular modem built into the basestation, I'm aware of this, but you should not have to purchase the paid subscription service for your system to function without an internet connection.The TS was unable to direct me anywhere on the website to confirm this so I'm hoping they have this wrong. Can anyone with a working system verify this.Many thanks, Dave
