App ver 7.88
If the message length is longer than the OLED display there is no indication it has been truncated and no was to see the remaining text. The message is displayed correctly in the app.
Would it be worth having an character limit option in the app? The problem with this would be that when the second part of the message arrives there is no way to see the first part.
All this is only an issue for units not connected to the app
