Battery drain due to snapshot capture

After the recent app update, the battery life of my Ring video doorbell 2 dropped from 2 weeks to 3 days. Replacing the battery with a spare one doesn't help. The app is suggesting me to turn off the snapshot capture feature, due to its high battery usage. However, when I go to the settings menu, this feature can't be turned off, and there's a warning that says "Snapshot Capture requires a Ring Protect subscription". Why can't I turn this feature off without a subscription?
