today one of my user get nil when call [[MobileRTC sharedRTC] getMeetingService] .
His device is ipad and ios version is 9.0. SDK version is: [v4.1.34076.1024]
According to previous topics
I check my code, I am sure my app first do auth successfully and then call getMeetingService. Among of thousand users only one user get this error.
so my question is: is there other reason leading to this error?
