Using the Line application on Android.
I see and read that it is possible to leave a group chat by clicking on the 3 bars on the top right, it gives you the option to leave.
But other chats that are with one person, not a group, I don't see this option.
Some old chats are listed as 'empty'. Click on it and at the bottom is says 'unknown left the chat', then 'you're the only one here' in the message field.
How do I do this myself and leave a chat without deleting my profile?
TIA.
