Hi @David_Thibaudeau,
Thank you for writing in to let us know about this issue. Can you provide the make and model of the head unit you are using?
Roon will give you a notification if you have a pending update. If there isn’t a notification then you are likely up to date. If you want to be sure you can open the Roon ARC setting by tapping the cogwheel. You will see the version number of ARC there.
