So far I’ve entered over 1,500 verses of hymn lyrics in Dorico. There is an odd spacing quirk that I often run into. In a system with plenty of room, two words will be too close to each other - sometimes even overlapping. If I nudge one of the words or enable the horizontal offset, Dorico will appear to “remember” about the spacing gap and move them apart the proper amount. My guess is that the spacing algorithm is somehow skipping over these words.
This picture shows the words with the default (incorrect) spacing:
This picture shows what happens when I turn on the horizontal spacing (set to zero):
