Only one user is able to access the app – Wisenet Life Review

My Dvr is Wisenet SDH-B84045BF. The problem is Only one user is able to access the app (Wisenet life) at a same time? The other Brand apps can access up to 7 Users at a same time. Also the resolution live cam in (wisenet life app) is very low. And can't change it to HD. I do not recommend this app and this DVR.
