I'm going to attempt to start a Lechange bug thread. Maybe it can help us sort out some of the issues ourselves. -Note: Hardware, Platform ( Android or IOS ) and any issue you are having. -Please be sure you have the most current Lechange App version before submitting any bug. Current android version : Updated April 21, 2018 Current Version 3.15.000 _______________________________________________________________________________________________________________________ Dahua 5216-4ks2 / Android : App connects to NVR fine but once the app is closed and re-opened it states "offline" logging into easy4ip.com shows that the NVR is indeed connected.
