I turn on the program, enter it, enter the IP address of the voice chat in the search bar, where I talk to my friends.
At the end of the conversation, I just turn off the phone from Wi-Fi.
The next day, I turn on Wi-Fi, and the program does not remember the last call.

I have to enter the IP address of the chat, again, to enter it.

The program is not understandable, and complex, for the average person. Having a local language will greatly simplify the setup task.
