Following up my issues with NP playback of trills and fermatas, after it was solved I noticed another situation that involves tempo changes and now it is independent of the Playback template.
Seems like tempo changes behave erratically, if ever at all, if they happen over tied notes, trilled or not. If there is a fermata before the tempo change, the fermata is ignored. The new tempo is also ignored or it is acknowledge some beats later, randomly. If no new tempo is set after the fermata, the tempo is slower, which also shouldn’t be the case. See a pic of the excerpt I have used for testing, I’m also uploading a file.
If there are no tied notes over the tempo changes and fermatas no problem is observed.

Dorico applies fermatas to notes but not to rests. When a fermata is attached to a rhythmic position, Dorico examines all of the notes which start at or continue through this rhythmic position, and the effect of the fermata lasts until the earliest rhythmic position at which one of those notes ends. In your example, the only note to which the first fermata applies is the tied note, and the effect of that fermata lasts until the tied note ends, which is not what you expected.
The simple solution is to suppress playback of both fermatas in your example and add hidden tempo changes at the rhythmic positions where those fermatas begin and end. The complicated solution is to create a new notehead set containing a quarter notehead that looks like a quarter rest and a half notehead that looks like a half rest, replace the rests to which the fermatas are attached with notes using this notehead set, suppress playback of these notes and hide their stems.
To learn more about how Dorico handles fermatas than you ever wanted to know, see this topic and this topic.
