Hi there,
I get the error message: “cannot read property ‘slice’ of undefined” when I want to send a message from the web interface. It doesn’t matter which channel I use. When I send a message from the app, only an empty field appears in the chat.

Does anyone have any idea why this is?

many Greetings
Sascha
