Dorico 4: embellishments

I would like to report a possible bug in Dorico 4.0.31.
When insert an “acciaccatura”, simple, double or triple, on the first note of the first bar, it is not reproduced, because Dorico handles this embellishment only on the upbeat.

Go to the Timing page of Playback Options and set Pre-roll before flow to something greater than zero seconds.

Thx Daniel.
