Endless mission's progress is stuck when not host. No timer or reward is obtained.

[india]

I did 4 waves of elite onslaught and the timer got stuck at wave 1 it self , the host got all the reward but i didnt received any thing except XP. this has been an issue with lot of endless mission and due to this i have lost many rewards on good long runs. Please see to this issue and solve it. i have the game play of this particular mission as well and will link the video in the post. This always happens when iam not the host and host has a bit laggy internet or bad one . if iam the host i have no issues at all. This is really frustrating.
