Devialet's answer on the stereo sync issue

[Walzu]

I haven’t received an email so far, but I used the update button in the app after reading your post. The app immediately started to download the patch. I had to do the update for each phantom. 
The firmware number changed on both. Unfortunately I had no time to test the phantoms after the update, but I will do tomorrow and report if the problem is solved in my case. I keep me fingers crossed for you and all the others that this update will bring back the joy of listening to phantoms.

What is the firmware version after the update? I tried the same, but no updates available..
