Monitor needs 5 seconds before printing

The first part of my sketch output does not print, unless I place a 5 second delay at the start of setup(), and before Serial.begin(9600).

Is there something I should be doing to get the monitor ready for receiving data from the sketch, besides introducing a 5 second delay into the sketch?

Hi @sthudium, I opened an issue about that, thanks for your report. Can you share your sketch and what board you are using?
