My video is not loading; it shows that the camera is online but the feed is buffering. 

Depending on your internet speed it may take the device up to 30 seconds to load your live video feed. 

The camera is not holding my WiFi settings and continues to show that the camera is offline.

Make sure your camera’s SSID password was entered correctly. Also, ensure that the camera is no further than 80 feet from your router. The range is important to have a stable connection.
