Just got this DCS-8010LH. Accessing the camera works perfectly thru the Dlink app.... as long as I am on wifi. Any wifi, not just at home.
But if I have to access it thru cellular data, it just says "loading" and never stops.
Firmware version is 1.00.04. My phone is an iPhone 8+ on the latest IOS, using Cricket as the provider. My router is an Asus RT-AX66U.
