Version: Firmware 13.1.3 + DOS 2.2.4 Date: 2019-02-12

I noticed the same issue! The downgrade from 13.1.3 to 13.0.0 works but the DOS doesn't downgrade. It stays at 2.2.4!! So it looks like we can't go back to DOS 2.2.2. After downgrading I can't play with Roon. The player says that the device is in use!

At Devialet they look into the possibility of a downgrade to DOS 2.2.2, it´s not as easy as it looks like, the chief engineer told me - just to let you know.

Thanks for information. Just have to wait and see then..

I'm curios! Thank you..
