New USPS Component options for scan_interval not working

Installation Home Assistant OS
1

Love the new USPS component that works with the new Hass.io v 0.52.

I am not able to get the image scans to go any faster. This link shows the options to change it.
USPS Camera

camera:
  - platform: usps
    scan_interval: 2

I have tried several scan intervals like 2,3, .5 and the images still rotate about every 6 seconds for me. Smartphone, tablets, all the same.

Any ideas?
