I have the Blynk 2 app installed on my iPhone and iPad The iPhone 10 and the iPad are at IOS level 14.6. I have a sketch that issues a terminal.clear(); at the end of the setup routine. Neither device clears the terminal window when the sketch is started.
The other problem is with terminal.flush(). The iPhone works correctly, but the iPad is very erratic. I issue a flush after each terminal.println , but the iPad will sometimes queue up a bunch of lines before being displayed.
