When a pilot connects to the mp-network using the `Compatibility` setting `Visible to only 2017+` there are no messages shown in the chat dialog. The pilots chat is kind of recive only.
How to reproduce:
- Start OR
- Start with a plane on the same airport
- Connect to mp with the `Compatibility` setting `Visible to only 2017+`
- Write somethin on the pilot side
- Take a look at the chat in OR
I see this bug as major since it's intended, to switch the default protocol to the new one:
