The application suddenly stopped, after I successfully deleted the message in the group section, then tries to reenter the group

[ammarraisafti]

Expected behavior

Delete the message in the group section and log back into it.

Actual behavior

The application suddenly stopped, after I successfully deleted the message in the group section, then tries to reenter the group.

How to reproduce

• Install the latest version of "Sky gear chat demo" app and open it and run the app.

• Once you have successfully logged in, you must create a group conversation.

• You should then try to send some messages in the group, then delete the messages that have been sent.

• Then you have to exit the group, then go back into it.

• You will find the problem as I have explained, the application suddenly stopped.

• Browser: Samsung Galaxy S6 edge

• Operating system: Nougat 7.0

• App version: 1.4
