If you go to the Dynon forum you will find a plethora of ideas on why 16 is not out yet. One of the beta testers says Dynon is working on features and the virus has slowed down work by injecting inefficiencies in the work environment. Go to Dynon forum and see for yourself.
For myself, I am not sure what is implied by the idea that "Dynon may have a problem". That is the kind of statement that can be read by some as insinuating that Dynon is defective in some way. I hope that is not the intent, because of course having confidence in one's avionics is important in aviation. I fly with Dynon and have had no problems that weren't the result of my own misunderstanding.
So, to be direct, I do not have any reason to believe that Dynon "has a problem". But go to the Dynon forum, read and put your thoughts there where Dynon is sure to see them.
