All, please be advised, that I would like to echo what @Mike has already stated here.
Devialet is aware of the mentioned behavior(s), as our techs have discussed this issue with them. We are hoping that our feedback will ultimately lead towards resolving the problem.
While I can not comment on an exact time frame as to when this will be fixed, I would recommend, monitoring the behavior of your Devialet devices, and checking in for further updates not only here but with Devialet as well.
The team greatly appreciates your understanding and continued patience!
