Hi support team,

I have a bug will happen every time.

start intent ZopimChatActivity, then press back before the chat session initialize complete.

Then the crash happen.

I have already upgrade the sdk version as below(Should be same version as the sample)

"com.zendesk:support:5.0.3"
"com.zopim.android:sdk:1.4.9"

Seems the crash is inside the sdk and I have no idea to fix the bug.

Does anyone have the same issue? Or any suggestion? Thank you.
